You can put this solution on YOUR website! First, divide both sides by 5. Then take the sqrt of both sides. and Don't forget every time you take a square root in a quadratic equation you always get plus and minus the answer.
The x-intercepts:to find an x-intercept you always substitute 0 in for y in the function. As you'll see, you get the same answer as you just got above.
The point is that solving an equation is the same as finding the function's x-intercepts.
