x = - 3/2 or + 2
Step-by-step explanation:
Write in standard form:
2x^2 - x - 6 = 0
Find factors of 2 (-6), the product of the first and last coefficients, that have a sum of - 1, the middle coefficient.
-12 = - 4·3
Split the middle term using those factors:
2x^2 - 4x + 3x - 6 = 0
Factor the pairs of terms:
2x (x - 2) + 3 (x - 2) = 0
(2x + 3) (x - 2) = 0
Use the zero product rule to identify solutions.
2x + 3 = 0 ⇒ x = - 3/2
x - 2 = 0 ⇒ x = 2
