Question

Find all common zeroes if the polynomials x3+5x2-9x-45 and x3+8x2+15.

Answer 1

Heya,
x+5 and x+3
Mark me brainly

Answer 2

Answer:

Step-by-step explanation:

P(x)=x3+5x2-9x-45=x2(x+5)-9(x+5)

P(x)=(x+5) (x2-9)

(X+5) (x+3) (x-3)

Q(x)= x3+8x2+15x

X(x2+8x+15)

X(x+5) (x+3)

Therefore,(x+5) and (x+3) are the two common zeroes.
