what else is the math problem
Step-by-step explanation:
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.
