Can you solve this radical equation? This TRICK will save you time!

Are you struggling with radical equations? In this math tutorial, I solve the equation √(5x²+4x) − √(x²−3x−18) = 5√x using a smart and structured method. Instead of jumping straight into messy squaring, I carefully rearrange the equation, square both sides, and rewrite the expression to match common factors. Then I use substitution (a = √(x²−6x), b = √(x+3)) to turn the equation into a simple quadratic form, which can be factorized easily. From there, I solve the resulting cases and apply domain restrictions to find the correct values of x. This method helps you avoid common mistakes and makes a difficult radical equation much easier to handle. If you’re preparing for exams like SAT, WAEC, or JAMB, or you just want to improve your algebra skills, this video will show you a clean and reliable approach you can use again and again.
