Question

Factor completely. 40s^2+34s−20 Enter the factors. Enter the original expression if it cannot be factored.

Answer 1

40s²+34s-20

divide each term by 2

2(20s²+17s-10)

20*10=2*2*5*2*5=(2*2*2)(5*5) and 25-8=17

2(5s    )(4s    ) so far

2(5s  2)(4s  5) so far

2(5s-2)(4s+5) is the answer
