Question

Factor and solve: -3p^2 - p - 2 = 0

Please show step by step and how to factor trinomials when the leading coefficient is a negative number.

Answer 1

Explanation:

-3p² - p - 2 = 0

a = -3; b = -1 c = -2

[-b ±√(b² - 4ac)]/2a = [1 ± √(1-4*-3*-2) ] /2*-3

=[1 ± √(1-48) ]/-6

= - [1 ±√-47]/6

= - [1 ±√47i]/6
