Question

What is the factorization of the polynomial below?

2x2 + 20x + 50

A. (x + 2)(x + 5)
B. (2x + 5)(x + 5)
C. 2(x + 5)(x + 5)
D. (x + 5)(x + 10)

Answer 1

the answer is C
2(x + 5)(x + 5)

Answer 2

c.

Explanation:

The equation is
`2x^(2) +20x+50`

First, we apply common factor

`2(x^(2) +10x+25)`

Then, we factorize the trinomial at the form (x+ )(x+ ) searching two numbers that multiplied are 25 and added are 10, in this case 5 and 5.

`2(x+5)(x+5)`.
