3x^2 = 60

Accepted Answer

Hello today we're going to solve this equation by using any of our preferred methods. So the equation given to us is five X squared equal to 75. And we're just gonna go ahead and solve this algebraic lee in order to solve for X. We need to get X by itself. And the first step in doing that is to divide the equation by five. Doing so is going to give me X squared is equal to And we need to get rid of the square. And in order to do that we could take the square root of both sides of the equation. That's going to give me X is equal to the square root of 15. Now we can't reduce the square root of 15 any further. So it's gonna stay as is. But keep in mind that whenever you take a square root of a number, you're given two values a positive and a negative value. So the solution to this equation is going to be when X is equal to plus or minus the square of 15. And that means that the answer to this problem is going to be C. So I hope this video helps you in understanding how to solve this type of equation. And I'll go ahead and see you all in the next video
