Solving Radical Equations with One or Two Radicals

In this video we talk about solving radical equations with one or two radicals. The general idea is to first isolate the radical, or one of the radicals, then raise both sides of the equation to the power of the radicals.

0:00 - sqrt(2x-3)=5
2:34 - x-2=sqrt(x)
9:25 - sqrt(4x-3)+3=2 vs cbrt(4x-3)+3=2
14:28 - sqrt(x)+sqrt(3x+4)=6

The last example has two radicals (two square roots). The idea is to isolate one of them first and square both sides. After that, we need to isolate the radical one more time and do the squaring. Then there will be no more square roots!
