Question

Find the polynomial x3 +8x2+15x

Answer 1

Answer:

x^3+15x+16

Step-by-step explanation:

x^3+16+15x

x^3+15x+16 is the polynomial

Answer 2

Answer:

let

P(x) = x 3+ 5*2-9x 45

and

let

p(x) =x 3 + 5x 2- 9x -45= x2 + (x+5) -9 (x+5) (x2-9)

Q(x) = x 3+8*2+15x=x(x2+8x+15)

=x(x+5) (x+3)
