How do I solve radical equations?
2 answers:
radical equation is solved by simply squaring or cubing both sides of the equation. For example:
(2x + 9) =5
(2x + 9)^2 =5^2
Then, continue to isolate the variable:
2x+9=25
2x + 9 - 9 = 25 -9
2x/2 = 16/12
X=8
Answer:
Isolate the radical expression.
Square both sides of the equation: If x = y then x2 = y2.
Once the radical is removed, solve for the unknown.
