How to solve x2 + 5x - 6 in factoring quadratics

(x + 6) (x-1)

Step-by-step explanation:

Find the factors of 6 first = 1,6 and 2,3

You must choose the set that when you add them together will make positive 5, but when you multiply them it must make a negative six since the last term is negative

So (x + 6) (x - 1) because if you add 6 + (-1) you get 5

and when you multiply 6 x - 1 you get - 6

Step-by-step explanation:

here

x² + 5x - 6

= x² + (6 - 1) x - 6

= x² + 6x - x - 6

= x (x + 6) - 1 (x + 6)

= (x + 6) (x - 1)
