Two numbers add to be 5 multiply to be -6

FrozenT [24]

Answer:

-1, 6

Step-by-step explanation:

x + y = 5

xy = -6

Take first equation and rewrite it. y = -x + 5

Then substitute the new equation in the second one.

x(-x + 5) = -6

-x^2 + 5x + 6 = 0

Divide by -1

x^2 - 5x - 6

(x + 1)(x - 6) = 0

x = -1, 6
