Question

Please help:

Divide 15x2 + 10x - 5 by 5x

i got it wrong the first time with the answer (3x^2+2x+1)/x

Answer 1

30 + 9x is what i've got, I'm not certain but hope this is correct!

Answer 2

x^2 + 3x - 18 divided by x - 3
you need to factor the numerator
(x + 6)(x - 3) / (x - 3)
divide numerator and denominator by (x - 3)
answer = x = 6
