Since the denominator is the same, just subtract the numerator:
(3x^2 + 2 - 9x + x^2)/(x^2 - 4) -->remember to use the distributive property with the negative over the terms in the numerator of the second fraction.
Combine like terms:
(4x^2 - 9x + 2)/(x^2 - 4)
Can we factor to reduce this fraction? Yes.
(4x - 1)(x - 2)/(x + 2)(x - 2)
Can you take it from here to reduce this fraction? (Hint: cancel out the same factors in both the numerator and denominator to reduce.)
I hope this will help.
thank you sooo much. now I know what I did wrong. First I got 2x^2 instead of 4x^2 and then I couldn't manage tpfactor because I didn't see were the nine would fit in. Thanks you for the help!
Answer this Question
find the equivalent fraction of 56/70 with a)numerator 4 b)denominator 10
A=1/2h (b1 + b2) Solve for b1 A=1/2h (b1 + b2) Solve for b1 I assume this is A = (1/2)(h)(b1 + b2); i.e., the h is in the numerator and not the denominator Multiply both sides by 2. 2A = (2*1/2)h(b1 + b2). 2*1/2 on the right side is 1. 2A = h(b1 + b2)

1. The numerator and denominator of a fraction are in the ratio of 3 to 4. If 4 is added to the numerator and subtracted from the denominator, the value of the resulting fraction is 4/3. The numerator of the original fraction is A. 12 B. C. 3 D. 4 2. If it
How many years is 140 CE to 1543?? That depends on whether you mean 1543 CE or BCE. If it's 1543 BCE, then you add the two numbers. If it's 1543 CE, then you subtract the larger from the smaller. =) A slight correction here: If it is 1543 BCE, then you add
A fraction equivalent to 45/60 if you were to multiply the denominator by the numerator the product would be 192
