Question

can someone show me step by step on how to solve this?: 3x^+21x-54
divided by:
x^2+3x-54

Answer 1

3x^ ? Please check your question.

Answer 2

3x^2

Answer 3

you simplify, which gives you 3(x-2)/x-6

Answer 4

how did you do that?

Answer 5

Okay so take the numerator and denominator one by one:
x^2+3x-54
We factorize it and we get: (x+9)(x-6)
And then the numerator: 3x^2+21x -54: 3(x+9)(x-2)
Then take the factorized forms in fraction form:
3(x+9)(x-2)/(x+9)(x-6)
We see x+9 gets cancelled:
So the answer is 3(x-2)/(x-6).
