Question

simplify (x + 1) (x +2) (x + 10).

Answer 1

Answer:

we are given (x+1) (x+2) (x+10)

for factorisation we have to maultiply all three terms ,that is

first we are multiplying (x+1) (x+2) we have ,

x² + 2x + x +2

x² + 3x + 2 --------- ( 1 )

now ,

we are multiplying last term that is (x+10) by above equation (1) we have ,

( x² + 3x + 2 ) ( x + 10 )

x³ + 10x² + 3x² + 30x + 2x + 20

x³ + 13x² + 32x + 20

FINAL ANSWER IS = X³ + 13X² + 32X + 20
