5x^2=45 How to simplify?

To simplify the equation 5x^2 = 45, we can start by isolating the variable x and finding its value. Here's how you can do it step by step:

1. Divide both sides of the equation by 5 to get the x^2 term on the left side alone:
(5x^2)/5 = 45/5
Simplifying:
x^2 = 9

2. To remove the square exponent, we can take the square root of both sides of the equation:
√(x^2) = √9
Simplifying:
x = ±3

So the solution is x = 3 or x = -3.

To summarize:
1. Divide both sides of the equation by the coefficient of x^2 to isolate the variable x.
2. Take the square root of both sides to eliminate the square exponent and solve for x.
Keep in mind that since we took the square root, we need to consider both the positive and negative roots as potential solutions.
