Question

Which are the solutions of x^2=-7-8?

Answer 1

Answer:

No Real Solutions

Step-by-step 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 2

Answer:

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

Step-by-step explanation:

$x^{2}$=-7-8

Simplify

$x^{2}$=-15

To isolate x square both sides:

$\sqrt{x}$=$\sqrt{-15$

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