WebOct 3, 2024 · Solution. We first need to isolate ( r + 4) 2 in order to apply the square root property. Then we can solve as usual. 5 ( r + 4) 2 + 1 = 626 Isolate the variable term 5 ( r + 4) 2 = 625 Isolate ( r + 4) 2 ( r + 4) 2 = 125 Apply the square root property r + 4 = ± 125 Solve for r r = − 4 ± 125 Simplify 125 r = − 4 ± 25 ⋅ 5 Apply the ... WebApr 9, 2024 · The strategy for solving is to isolate the square root on the left side of the equation and then square both sides. First subtract 2 from both sides: √x − 3 = 4. Now that the square root is isolated, we can square both sides of the equation: (√x − 3)2 = 42. Since the square and the square root cancel we get: x − 3 = 16.
