Will someone explain how to solve this?

Write each equation in standard form. Solve by using the Quadratic Formula.

this has been answered already. Reiny just stated that since x^2 is always positive, there's no real value of x which can produce -7 when squared.

Damon actually wrote the quadratic in standard form, applied the formula and gave the complex solutions.

Just what is it that is still bothering you?

1. -7 = X^2

x^2 + 7 = 0

X =( -B +- sqrt(B^2-4AC))/2A

X = (0 +- sqrt(0-28))/2 =

sqrt(28*(-1))/2 = 5.29i/2 = +-2.65i
