Factor the polynomial. 2y2 – 14y + 20 a.(y + 2)(y + 5) b.2ly - 2)(y + 5) c.(y-2)(x - 5) d.2(y-2)(y-5)

D

Step-by-step explanation:

Given

2y² - 14y + 20 ← factor out 2 from each term

= 2(y² - 7y + 10)

To factor the quadratic

Consider the factors of the constant term (+ 10) which sum to give the coefficient of the y- term (- 7)

The factors are - 2 and - 5, since

- 2 × - 5 = 10 and - 2 - 5 = - 7, so

y² - 7y + 10 = (y - 2)(y - 5) and

2y² - 14y + 20 = 2(y - 2)(y - 5) → D

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6
