(4x2 - 25)(x + 2)

(2x - 2)(2x + 2)(x + 5)

(2x - 5)(2x + 5)(x + 2)

(2x - 5)(2x + 5)(x - 2)

Answer 1

Given the polynomial 2x3 + 18x2 - 18x - 162, what is the value of the coefficient 'k' in the factored form?

2x3 + 18x2 - 18x - 162 = 2(x + k)(x - k)(x + 9)

k= ____________

Answer for Blank 1:

Answer 2

i just need a little help if u want u can just give the answers up to u

Answer 3

Look at the First one. And Split the Equation in 2. So Factor \[4x^3+8x^2\] And Factor \[-25x-50\]

Answer 4

Then tell me what you get c:

Answer 5

4x\[4x^3+8x^2= 4x^2(x+2)\]

Answer 6

Yess, And do the Samme for the other one. \[4x^2(x+2)-(25x-50)\]

Answer 7

the 2nd one is\[-25(x-2)\]

Answer 8

Try again.

Answer 9

Remember, two negatives make a positive, and it isnt positivee.
