Answer 4

hmmm well... what did you get from the multiplication then?

Answer 5

x3 - x2 - 26x - 24
Don't know if its right

Answer 6

hmm what does (x+6) (x+4) give you?

Answer 7

X^2+4x+6x+24

Answer 8

just the non-simplified version... maybe you missimplified

Answer 9

@jdoe0001

Answer 10

yeap that is correct
so that simplifies to \(\bf x^2+10x+24 \implies (x^2+10x+24 )(x-1)
\\ \quad \\
\implies x^3+10x^2+24x-x^2-10x-24
\\ \quad \\
\implies x^3+9x^2+14x-24\)
