# What is the first step in solving the quadratic equation -5x^{2} + 8 = 133 is to subtract from each side.

Taking the square root of both sides of the equation

Subtracting 8 from both sides of the equation

Squaring both sides of the equation

Adding 8 to both sides of the equation

**Solution:**

Complex numbers are the numbers that are expressed in the form of a+ib where, a,b are real numbers and ‘i’ is an imaginary number called “iota”.

-5x^{2} + 8 = 133 [Given]

Let us solve this quadratic equation.

Subtract 8 from both sides to isolate the variable.

-5x^{2} + 8 - 8 = 133 - 8

By further calculation

-5x^{2} = 125

So we get

x^{2} = 125/-5

x^{2} = - 25

Here

x^{2} = - 25 = (5i)2

x = ± 5i

Therefore, the first step in solving the quadratic equation is subtracting 8 from both sides of the equation.
