Question

x^3+13x^2+32x+20
factories this sum

Answer 1

Answer:

x^3+13x^2+32x+20

x^3 + x^2 + 12x^2 + 32x + 20

x^2 (x + 1) + ( 12x^2 + 32x + 20)

x^2 (x + 1) + ( 12x^2 + 12x + 20x + 20)

x^2 (x + 1) + 12x(x + 1) + 20(x + 1)

(x + 1) + (x^2 + 12x + 20)

by using splitting the middle term= x^2 + 12x + 20

x^2 + 10x + 2x + 20

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

(x + 1) (x + 10) (x + 2)
