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

You need to isolate the squared term on one side, therefore, you need to do the second one, first

Answer 2

The first step is subtract 8 from both sides of the equation

Then you take the square root of both sides of the equation

Finally you divide from both sides op the equation by -5

-5x2+8=133

-5x2 + 8 - 8 = 133 - 8

-5x2 = 125

-5x = √125

-5x = 11.18

-5x / -5 = 11.18/-5

x = 2.236

Answer 3

subtracting 8 from both sides of the equation
