Q:

Which method most efficient method to solve x2+5x-6=0

Accepted Solution

A:
Factoring is the best method to factor this, as it’s easier and quicker to use. -6 and 1, when multiplied, get the c value (-6) and when added together get the b value (5). So then you take the opposite of them, 6 and -1, and that’s your answer.

x=-1 or 6
