%28-+5%28-+2%29%283x%5E2+%2B+2x+-+1%29%29%2F%28-+5%29 ----- Factoring out GCF, 10, or - 2(- 5) in numerator

%28cross%28%28-+5%29%29-+2%283x%5E2+%2B+2x+-+1%29%29%2Fcross%28-+5%29 ------ Cancelling - 5 in numerator and denominator

You're left with: highlight_green%28-+2%283x%5E2+%2B+2x+-+1%29%29, which is what you got. Good job!!
