multiplication

Answer 3

could you explain a little please? c:

Answer 4

example : what do you have to do with 2 and 3 to get 6? multiply so 2 *3 = 6
what do you have to to with d and d to get d^2 multiply

if you want to get x^3 and you have x^2 you need to multiply by x since x^3 = x^2 *x

Answer 5

the question ask what you you have to do with (x^2-9) and (-x + 7) to get a term with x^3?
