Answer:

No Real Solutions

Explanation:

Move the constants to the left now your equations is
x^(2)-7+8=0

Now you calculate -7+8=0 now your equation is
x^(2)+1=0

Calculate the discriminant: Determine the number of solutions using the discriminant D=
b^(2)-4ac

D=
0^(2)-4 x 1 x 1

Simply the expression

D= -4

Since D<0, the quadratic equation has no real solutions

Answer:

I don't think there are any solutions... (No solution)

Explanation:


x^(2)=-7-8

Simplify


x^(2)=-15

To isolate x square both sides:


√(x)=
\sqrt{-15

-15 cannot be squared since it is negative. Therefore, there is no solution.
