Times both sides by -1
-8x=x²-20
add 8x both sides
0=x²+8x-20
factor
what 2 numbers multiply to get -20 and add to get 8
-2 and 10
0=(x-2)(x+10)
set to zero
x-2=0
x=2
x+10=0
x=-10
x intercepts at x=-10 and 2 or at the points
(-10,0) and (2,0)
Witch one do you need help with?
2 1/2 * 3
5/2 * 3/1
= 15/2
15/2 - 11 3/8
15/2 - 91/8
91/8 - 60/8
= 31/8 = 7 7/8
