solve 4 X , x^2=2x+48?

Answer 1

x^2 = 2x + 48
Transferring all to the left
x^2 - 2x - 48 = 0
Factorizing
(x - 8)(x + 6) = 0

x - 8 = 0 and x + 6 = 0
x = 8 and x = -6

Answer 2

You gotta do some factoring here.

First, set everything equal to zero.

Now you havex^2-2x-48=0

Factored, this comes out to:

(x+6)(x-8)=0.

To get the answer, take the opposite of what is inside the brackers, i.e. because it says (x+6), that part of the answer is x=-6.

Full answer: x=-6 and 8.

Answer 3

x^2=2x+48
x^2-2x-48=0
(x-8)(x+6)=0
x=8,-6

Check:
(-6)^2 = 36
2(-6)+48 = -12+48 = 36
and
(8)^2 = 64
2(8)+48 = 16 + 48 = 64
