Answer:
x = -3/2, 1. It is Choice 3.
Step-by-step explanation:
2x^2 + x - 3 = 0
Use the 'ac' method:-
2* -3 = -6 so we need 2 numbers whose produce is -6 and whose sum is +1 .
They are = +3 and - 2. So we write
2x^2 - 2x + 3x - 3 = 0
Factor by grouping:-
2x(x - 1) + 3(x - 1) = 0
(2x + 3)(x - 1) = 0
giving x = -3/2 , 1.

The number of movie rentals would be 30
To find the answer you have to do this
(M stands for movies)
$25 + 2m = $10 + 2.50m
-10 -2m -10 -2
$15 = .50m
Divide .50/15
You get 30
Check your answer $25 + 2(30) = $10 + 2.50(30)
$25 + $60 = $10 + $75
$85 = $85
