2x² + 16x + 30 

<span>Step 1: Solve the quadratic equation to get <span>x1</span> and <span>x2</span>.</span> In this example 

we have: x₁ = −3     and     x₂ = −5

Step 2: To find factored form we use formula

<span>ax</span>²+bx+c=a(x−x₁)(x−x₂)

<span>a=2 , b=16 , c=30 , <span>x1</span>=−3 , <span>x2</span>=−5
Substitute the values, 
It would be: 2(x+3)(x+5)

In short, Your Answer would be Option B

Hope this helps!</span>

2x² + 16x + 30

2(x² + 8x + 15)

So we factorize (x² + 8x + 15)

As long as the coefficient of x², is 1. we look at the last term, 15 and think of two numbers that multiply to 15 and add up 8.

15 = 3*5            3 + 5 = 8

x² + 8x + 15

x² + 3x + 5x + 15

x(x + 3) + 5(x + 3)

(x + 3)(x + 5)

2(x² + 8x + 15) = 2(x + 3)(x + 5)

Option B.
