Will someone explain how to solve this?
Write each equation in standard form. Solve by using the Quadratic Formula.
1. 7 = x^2

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^24AC))/2A
X = (0 + sqrt(028))/2 =
sqrt(28*(1))/2 = 5.29i/2 = +2.65i
