Question

If you're solving a quadratic equation by factoring

what would the factorization of g(x)=x^2+12x+20

Answer 1

Explanation:

Product = 20

Sum = 12

Factors = 2 , 10 {2*10 = 20 & 2+10 = 12}

x² +12x + 20 = x² + 2x + 10x + 20 {Split the middle terms using the factors}

= x( x + 2) + 10(x + 2)

= (x + 2)(x + 10)
