WebSquare both sides, and x^2 = 4. For some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x is only equal to 2. Therefore -2 is an extraneous solution, and squaring both sides of the equation creates them. 1 comment ( 23 votes) Upvote

WebSolution: Given, the equation is; 3 + x = 4 We can see, on the Left hand side, the variable x is present. Thus, we need to make the variable ‘x’ alone on LHS. Thus, by subtracting the 3 from LHS and RHS we get; 3 + x – 3 = 4 – 3 x = 1 Hence, the solution is x = 1. Verification: For x = 1 Taking LHS and proving it equal to RHS. WebHow to solve for exponents For x n = y; solve for n by taking the log of both sides of the equation: For: x n = y Take the log of both sides: log x n = log y By identity we get: n ⋅ log x = log y Dividing both sides by log x: n = log y … WebCompleting the square method is a technique for find the solutions of a quadratic equation of the form ax^2 + bx + c = 0.
