Question

What is the first step in solving the quadratic equation -5x2 8=133? 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

Answer 1

The first step in solving the quadratic equation -5x2 + 8 = 133 is to subtract 8 from both sides of the equation.

For better understanding Let us solve this quadratic equation

The first step is to subtract 8 from both sides to isolate the variable.

-5x2 + 8 - 8 = 133 - 8

-5x2 = 125

x2 = 125/-5

x2 = - 25

 x2 = - 25 = (5i)2

x = ± 5i

Therefore, from the above, we can  say that The first step in solving the quadratic equation -5x2 + 8 = 133 is to subtract 8 from both sides of the equation.
