Checking square roots, we see that 52 = 25 and 62 = 36 Our answer is not an integer, so we try simplify it into the product of an integer and a radical.
We do this by listing each product combo of 28 checking for integer square root values below:
√28 = √1√28 √28 = √2√14 √28 = √4√7
Find the highest integer square root
The highest factor that has an integer square root is 4 Therefore, we use the product combo √28 = √4√7 Evaluating square roots, we see that √4 = 2
Solve for y
Group our variables and subtract from both sides --
Cancel on the right side:
Divide each side of the equation by 0

What 3 formulas are used for the Equation and Inequalities Calculator?
One Step Equations (Division):
cx = b
x = b/c
One Step Equations (Addition):
x + c = b
x = b - c
One Step Equations (Subtraction):
x - c = b
x = b + c
