Answer:
5x^2+8x-20
Step-by-step explanation:
Group them 1st as you see they are all divisible by 2 so well factor it
from:
10x^2+8x-20 into:
2(5x^2+8x-20) Divided by 2
Cancel the 2 on the numerator and the denominator
so the final answer is:
5x^2+8x-20
I used this way of division because on more difficult problems you will encounter something like this:
(x-1)(x+1) divided by (x^2-1)(x+1)
where you fill be forced to factor or simplify several expressions to find the answer hope it helps hehe
