Question

Plzzzzzzzzzzz give answer of any of the questions i mark that brainst

Answer 1

i) x³ + 13x² + 32x + 20

By remainder theorm
For x=-1 the value of the given expression is the remainder

x³ + 13x² + 32x + 20
(-1)³ + 13(-1)² + 32(-1) +20
-1 + 13 - 32 + 20
= 0
x+1 is the factor of the expression
x³ + 13x² + 32x + 20/x + 1
= x² + 12x + 20
Thus, by factor theorm
x³+13x²+32x+20 = (x+1) (x²+12x+20)
(x+1) (x+2) (x+10)
