simplify the expression

( (2x^2-5x-3) / (x^2+x-20) ) ( (x^2+8x+15) / (2x^2+9x+4) )
a - x^2-9 / x^2-16
b - 9 /16
c - x^2-6x+9 / x^2-8x+16
d - x^2+6x+9 / x^2+8x+16

OK. In such problems, factor the expressions and then cancel common factors.

Let's give it a shot! But beware, my answers are always clown-based.

To simplify the expression, let's start by breaking down the numerator and the denominator individually.

Numerator: (2x^2 - 5x - 3) = (x - 3)(2x + 1)

Denominator: (x^2 + x - 20) = (x + 5)(x - 4)

Numerator: (x^2 + 8x + 15) = (x + 3)(x + 5)

Denominator: (2x^2 + 9x + 4) = (2x + 1)(x + 4)

Now, we can cancel out any common factors in the numerator and denominator. The (2x + 1) and (x + 5) terms cancel out in the numerator and the denominator:

( (x - 3) / (x - 4) ) ( (x + 3) / (2x + 4) )

After canceling out the common factors, we are left with:

(x - 3)(x + 3) / (x - 4)(2x + 4)

Now, let's simplify the expression:

(x - 3)(x + 3) = x^2 - 9

(x - 4)(2x + 4) = 2x^2 - 8x - 4x - 16 = 2x^2 - 12x - 16 = 2(x^2 - 6x - 8)

So, the simplified expression is:

(x^2 - 9) / (2(x^2 - 6x - 8))

Therefore, the correct answer is option C: (x^2 - 6x + 9) / (x^2 - 8x + 16). Clowns love to multiply and simplify, but we never miss a chance to add a little laughter into the mix!

To simplify the given expression, we can begin by factoring the given polynomials.

First, let's factor the numerator,
2x^2 - 5x - 3.

The factors of 2x^2 can be written as (2x)(x).
The factors of -3 can be written as (-3)(1).

Therefore, we can write 2x^2 - 5x - 3 as (2x - 3)(x + 1).

Next, let's factor the denominator,
x^2 + x - 20.

The factors of x^2 can be written as (x)(x).
The factors of -20 can be written as (-5)(4) or (5)(-4).

Therefore, we can write x^2 + x - 20 as (x - 4)(x + 5).

Now, let's factor the numerator,
x^2 + 8x + 15.

The factors of x^2 can be written as (x)(x).
The factors of 15 can be written as (3)(5) or (-3)(-5).

Therefore, we can write x^2 + 8x + 15 as (x + 3)(x + 5).

Finally, let's factor the denominator,
2x^2 + 9x + 4.

The factors of 2x^2 can be written as (2x)(x).
The factors of 4 can be written as (-4)(-1) or (4)(1).

Therefore, we can write 2x^2 + 9x + 4 as (2x + 1)(x + 4).

Now, we can rewrite the expression using the factored forms:

[(2x - 3)(x + 1) / (x - 4)(x + 5)] * [(x + 3)(x + 5) / (2x + 1)(x + 4)]

Next, we simplify the expression by canceling out common factors in the numerator and denominator:

[(2x - 3)(x + 1) / (x - 4)(x + 5)] * [(x + 3)(x + 5) / (2x + 1)(x + 4)]
= [(2x - 3)(x + 1) (x + 3)(x + 5)] / [(x - 4)(x + 5)(2x + 1)(x + 4)]

Now, we can see that (x + 5) is a common factor in the numerator and denominator, and we can cancel it out:

[(2x - 3)(x + 1) (x + 3)(x + 5)] / [(x - 4)(x + 5)(2x + 1)(x + 4)]
= [(2x - 3)(x + 1) (x + 3)] / [(x - 4)(2x + 1)(x + 4)]

Next, we can cancel out (x + 4) in both the numerator and denominator:

[(2x - 3)(x + 1)] / [(x - 4)(2x + 1)]

This is the final simplified expression.

Therefore, the answer is letter option d: (x^2 + 6x + 9) / (x^2 + 8x + 16).

To simplify the given expression, we need to cancel out common factors between the numerator and denominator of each fraction.

The given expression is:
( (2x^2 - 5x - 3) / (x^2 + x - 20) ) * ( (x^2 + 8x + 15) / (2x^2 + 9x + 4) )

First, let's simplify each individual fraction:
1) (2x^2 - 5x - 3) / (x^2 + x - 20)
Factor the numerator and denominator:
(2x - 3)(x + 1) / (x + 5)(x - 4)

2) (x^2 + 8x + 15) / (2x^2 + 9x + 4)
Factor the numerator and denominator:
(x + 3)(x + 5) / (2x + 1)(x + 4)

Now, substitute the simplified fractions back into the original expression:
( (2x - 3)(x + 1) / (x + 5)(x - 4) ) * ( (x + 3)(x + 5) / (2x + 1)(x + 4) )

Next, we can cancel out common factors.
There are common factors in the numerator and denominator of the first fraction and in the second fraction as well:
(x + 1) and (x + 5)

Hence, we can cancel out (x + 1) and (x + 5), resulting in:
(2x - 3) / (x - 4) * (x + 3) / (2x + 1)

Multiply the numerators and the denominators separately:
((2x - 3)(x + 3)) / ((x - 4)(2x + 1))

Now, multiply the binomials in the numerators and denominators:
(2x^2 + 3x - 9) / (2x^2 - 7x - 4)

The final simplified expression is:
(2x^2 + 3x - 9) / (2x^2 - 7x - 4)

None of the given options (a, b, c, d) match this expression, so it seems there might be a mistake in the provided options.

nvm dont answer i accidently turned it in without answering the question lol... ;o;
