Question

Find the solutions to x^2-10+36=0

Answer 1

Only 6

Explanation:

We need to factor the equation to find the solution. TO factor we need to find what times what = 36, and what plus what equals -12.

-6 times -6 = 36

and -6 + -6 = -12

So this can be factored into

(x-6)(x-6)=0

We can find the solution by setting each parentheses equal to zero.

x-6 = 0

x = 6

So the only solution is 6
