Solve (-3x^2) + 4 = 0 by completing its square. !

The answer for (-3x^2) + 4 = 0 is x = 1.155 which is solved using simple algebra to find the x value from the equation. First, move 4 to the right side of the equal sign, thus we will see the -3x^2 = -4 equation, then, divide -4 by -3 so we can find the squared number of x resulting x^2 = 1.333. We can finish the problem by finding the square root number of 1.333 which is possible to be done because 1.333 is not an imaginary number.

A) if x> 3, then x> 0this is the correct answer.
