Question

Pls solve this problem .Question no 12

Answer 1

Given Equation is x^3 + 13x^2 + 32x + 20

= > x^3 + 12x^2 + x^2 + 20x + 12x + 20

= > x^3 + 12x^2 + 20x + x^2 + 12x + 20

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

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

= > (x + 1)(x^2 + 2x + 10x + 20)

= > (x + 1)(x(x + 2) + 10(x + 2))

= > (x + 1)(x + 2)(x + 10).

Therefore, factorization of x^3 + 13x^2 + 32x + 20 = (x + 1)(x + 2)(x + 10)

Hope this helps!
