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 BHope 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.
