Example: x=7 ⇒square both sides ⇒ ( ) =( )2 ⇐ 2 x 7 The square and square root cancel out on the left. So, x=(7)2 ⇒ x=49Done! Note: The radical must be isolated on one side of the equal sign before you can square both side. Example: Solve 2 x−5+3=21 The radical is not isolated. 2 x−5+3−3= 21−3 ⇐ Subtract the three first from ...

Finding Square Roots Using Newton’s Method Let A > 0 be a positive real number. We want to show that there is a real number x with x2 = A. We already know that for many real numbers, such as A = 2, there is no rational number x with this property. Formally, let fx) := x2 −A. We want to solve the equation f(x) = 0.
