x cube + 13 x square + 32 X + 20
Answers
Answer:
Hey mate, please mention full question.
I am factorising it .
x³ + 13x² +32x +20
So, first of all , by hit and trial method
(x+1) is a factor .
so, divide x³ + 13x² + 32x + 20 by x+1
on dividing ,we get x² + 12x + 20
now,
x² + 12x + 20
= x² + 10x + 2x + 20
= x(x+10) + 2(x+10)
= (x+2) (x+10)
(x+1) , (x+2) , (x+10) are the factors of the given polynomial.
if we have to find the zeroes ofbthe polynomial
then,
-1 , -2 , -10 are the zeroes of the given polynomial.
Hope it helps you!!!

Question
x³ + 13x² + 32x + 20
Let's solve it
▶️ x³ + 13x² + 32x + 20
▶️ x³ + x² + 12x² + 12x + 20x + 20
▶ x²(x + 1) + 12x(x + 1) + 20(x + 1)
️▶ (x + 1) (x² + 12x + 20)
️▶ ️(x + 1) (x² + 2x + 10 + 20)
▶ (x + 1) (x(x + 2) + 10(x + 2))
️▶ (x + 1) (x + 2) (x + 10)
So, factors are :- (x + 1) (x + 2) (x + 10)
