Question

Is 6 a solution to the equation x2 - 4 =5x

Answer 1

4/7

Explanation:

x2-4= 5x

= +x2

-4=7x

/7

Answer 2

No.

Explanation:

Let's verify that the left-hand-side and -right-hand-side are different, when we replace x by 6:

(6)^2-4=36-4=32

5(6)=30

As 32 is different from 30, then 6 is not a solution of the equation.
