Question

Solve the quadratic equation 5x2 - 125 = 0.

Answer 1

Add 125 to both sides and then divide by 5.

As a last step, take the positive and negative square roots.

Answer 2

try \(5x^2=125\) then divide by 5
and finally take the square root, don't forget the \(\pm\)

Answer 3

5x^2 - 125 = 0 -> 5x^2 = 125

x^2 = 125/5 = 25 -> x = +- sqrt(25)

x = +- 5
