6x^4+3x3-2x^2+15x-14
a. 5
b. 4
c. 3
d. 2
oops I chose c. Is this correct??
there are five I believe. Is the three in 3x3 suppose to be 3x^3?
YES! #1Student
it is sorry
the powers don't really matter.
The terms are separated by the + and - signs.
So, just count them and add 1.
15x - x5+ 2x2 -9 + 3x3
To find the value of the expression 6x^4 + 3x^3 - 2x^2 + 15x - 14, you can substitute the given values of x from the answer choices (5, 4, 3, 2) into the expression and evaluate it.
Let's start with option a) x = 5:
Substituting x = 5 into the expression, we get:
6(5)^4 + 3(5)^3 - 2(5)^2 + 15(5) - 14
Now we can solve it step by step:
Step 1: Evaluate exponents:
6(625) + 3(125) - 2(25) + 15(5) - 14
Step 2: Perform multiplication:
3750 + 375 - 50 + 75 - 14
Step 3: Combine like terms:
3750 + 375 - 50 + 75 - 14 = 4136
Therefore, when x = 5, the expression evaluates to 4136.
Now you can repeat the same steps for the remaining answer choices (b) 4, (c) 3, and (d) 2 to find the value of the expression for each choice.
