How to Evaluate Equations that Have Square Roots - Square root equations are now intimidating by once understanding the idea behind them and solving them actually can be a long trip steps. So, here is an example of sqrt root eq: √x – 3 = 5. In such cases, you need a double check on two things: Square root must definitely by itself And the value of the other must a positive number Why this is important? The positive square root has to give you a positive numbers. If you have a positive square root and the negative number on the other side, it makes no sense. Here, because of the square root you have to do the opposite operation. Now apply 2 on both sides: √(x – 3) 2 = 5 (2). Then, the square & square root will cancel together. And, the equation will be: X - 3 = 25. Here, the solution has become simpler and you have to further solve it for the value of x. For this, you will shift -3 towards the other and its sign will change into positive: X = 25 + 3 | X = 28. If you want to check your answer, put the value of x in the question that we have supposed.
