Answer:
none
Step-by-step explanation:
(2x+3)(4x^2-5x+6)
factor over
8x^3-10x^2+12x+12x^2-15x+18
combine like terms
8x^3 + 2x^2 - 3x + 18
Answer: Do the opposite 27/3=9

So,
We are trying to figure out when Grandpa Lopez's age was twice that of Dad.
Let x represent the number of years before/after when G. Lopez's age was twice that of Dad.
66 + x = 2(37 + x)
Distribute.
66 + x = 74 + 2x
Subtract x from both sides.
66 = 74 + x
Subtract 74 from both sides.
-8 = x
So 8 years ago, G. Lopez was twice as old as Dad. Let's check that.
66 - 8 = 58
37 = 8 = 29
29 * 2 = 58
58 = 58
It checks.
The expression is (2x2)+5
