Question

factorize x^3+13x^2+32x+20 by regrouping terms method only?!​

Answer 1

Answer:

let x= 20 and put the value of x in above eq and solve

Answer 2

Answer:

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

Step-by-step explanation:

The value of x³+13x² +32x+20 is

x³ +x ² +12x²+12x+20x+20

=x² (x+1)+12x(x+1)+20(x+1)

=(x−1)(x² +12x+20)

=(x−1)(x² +10x+2x+20)

=(x+1)[x(x+10)+2(x+10)]

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