Question

How do you simplify this?

Answer 1

\[x ^{2}+2x-15/x ^{2}+3x-10\]

Answer 2

You'd have to factor the numerator and the denominator

Answer 3

Hint:
\[\frac{x^2 + 2x - 15}{x^2 + 3x - 10} \implies \frac{(x+5)(x-3)}{(x+5)(x-2)}\]

Answer 4

I don't understand what you have to do after that

Answer 5

\[\large \frac{(x+5)}{(x+5)}*\frac{(x-3)}{(x-2)}=1*\frac{(x-3)}{(x-2)}\]

Answer 6

\[\frac{\cancel{(x+5)}(x-3)}{\cancel{(x+5)}(x-2)}\]

Answer 7

that's what happens

Answer 8

by saying \[x2+2x−15/x2+3x−10\] did you mean \[(x2+2x−15)/(x2+3x−10) \]?

Answer 9

Really sorry, but I'm still a bit confused.

Answer 10

@lexbryan yes

Answer 11

then @lgbasallote is correct.
