No yes yes yes no ; sol. when x=4 , f(x) = 0 ,so (x-4) is right answer.....
Answer: YES → (x + 2) (x - 4) (x + 4)
NO → (x - 2) (x + 6)
<u>Step-by-step explanation:</u>
The best way to answer this question is to factor the given polynomial and then look at the choices at the botom of your screeen.
f(x) = x³ + 2x² - 16x - 32
0 = x³ + 2x² - 16x - 32
= x²(x + 2) -16(x + 2)
= (x + 2)(x² - 16)
= ↓ (x - 4)(x + 4)
= (x + 2)( x - 4)(x + 4)

May i ask is it 3+26 or is there more
X²-8x=3
x²-8x+16=3+16=19
(x-4)²=19
x-4=±√19
x=4±√19
x=8.3589 approx or x=-0.3589 approx {4-√19,4+√19} or {-0.3589,8.3589}
