5x^2-1=74

You can put this solution on YOUR website!
5x%5E2-1=74
==================
First, get the x^2 term alone on one side of the equation:
5x%5E2=75
x%5E2=15
To solve for x, take the square root of both sides of the equation:
x=+-sqrt(15)
This can't be simplified further, so you are done. You can check your answer by plugging both results (the plus and the minus) into the original equation and confirm that the equation holds true.

Good Luck,
