Question

− x^2+10=6 can anyone explain me how to do this please ?

Answer 1

x = -2 or 2

Explanation:

-x² + 10 = 6

Move everything to one side. I suggest moving the left side to the right so that the leading coefficient becomes positive.

0 = x² − 4

Factor the difference of squares:

0 = (x − 2) (x + 2)

Set each factor to 0 and solve.

x − 2 = 0

x = 2

x + 2 = 0

x = -2

Therefore, the solution is x = -2 or 2.

Answer 2

Explanation:

Step 1: -x^2 is -1 because x is always 1.

Now that you found your first step take -1x+10=6. You're going to subtract 10 from both sides which leaves you with a sum of -4. So -1x= -4 now divide -4/-1x which gives you a positive number.
