How do you simplify

this is a fraction, not a division problem. Not supposed to solve, just simplify.

minus the x^2...
5x^2 minus 2...
is 3...
10x-5x is 5
so...
3x^2-5x-12/10

2x^2 + 10x + 12/5x^2 + 5x - 10
add 2x^2 & 12/5x^2 and you get 22/5x^2
collect like terms: 10x + 5x= 15x
leave 10 alone b/c it doesnt have any like terms
so you get:
22/5x^2 + 15x - 10

2x^2+10x+12 / 5x^2+5x-10
2(x^2+5x+6) / 5(x^2+x-2)
2(x+6)(x-1) / 5(x+2)(x-1)
the (x-1) cancel so u're left with:
2(X+6) / 5(X+2).
AND THAT'S IT! : )

hey,
if you factorise the top and then factorise the bottom?
heres the answer: [(2x+4)(x+3)]/[(5x-5)(x+2)]
thats if you do that.
