WebJun 1, 2015 · A less direct, but perhaps simpler approach is to recognise that if x2 + 4x −21 has linear factors, then they must look like: (x +p)(x − q) = x2 +(p −q)x − (p ×q) where p,q > 0. The reason I say it must look like this with one + and one − is because the sign of the constant term in the original quadratic is negative. Then p − q = 4 ... WebSolve by Factoring x^2-4x=0. Step 1.

WebSolve Quadratic Equation by Completing The Square. 3.2 Solving 4x2-x-2 = 0 by Completing The Square . Divide both sides of the equation by 4 to have 1 as the coefficient of the first term : x2- (1/4)x- (1/2) = 0. Add 1/2 to both side of the equation : x2- (1/4)x = 1/2. Now the clever bit: Take the coefficient of x , which is 1/4 , divide by two ...
