Answer:
20
Step-by-step explanation:
You use the distributive property.

Substitute the answers above into the parentheses.
(8+12)=20
Answer:
(7, 0), (-8, 0), (0, 0)
Step-by-step explanation:
y = f(x) = 0
the real solutions are the ones that cross the x-axis because when a point is on the x-axis, its y coordinate will be 0.
=> (7, 0), (-8, 0), (0, 0)
