Factor the trinomial completely.
2x^4 -20x^2+ 32

2(x² - 2)(x² - 8)

Step-by-step explanation:

Given

2 - 20x² + 32 ← factor out 2 from each term

= 2( - 10x² + 32)

let u = x², then

- 10x² + 32 = u² - 10u + 32 = (u - 2)(u - 8)

change u back to x²

- 10x² + 32 = (x² - 2)(x² - 8) and

2 - 20x² + 32 = 2(x² - 2)(x² - 8) ← in factored form

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis
