Question

(i) x^3 + 13x² + 32x +20, if it is given that x + 2 is its
factor. plzz explain it... then only I will mark you brainiliest​

Answer 1

Explanation:

x+2=0

x= -2

x^3+13x^2+32x+20=0

(2)^3+13(2)^2+32(2)+20=0

8+13X4+64+20=0

8+52+64+20=0

60+64+20=0

124+20=0

144≠0

and hence, x+2 is not a factor of this equation

Answer 2

Answer:

The value of x³+13x²+32x+20 is

x³+x²+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)
