2.2 Solving x2-x-1 = 0 by Completing The Square . Add 1 to both side of the equation : x2-x = 1. Now the clever bit: Take the coefficient of x , which is 1 , divide by two, giving 1/2 , and finally square it giving 1/4. Add 1/4 to both sides of the equation : On the right hand side we have : 1 + 1/4 or, (1/1)+ (1/4)Exp. Solve sin 2x - 2sin x = 0 Solution. Transform the equation into 2 basic trig equations: 2sin x.cos x - 2sin x = 0 2sin x(cos x - 1) = 0. Next, solve the 2 basic equations: sin x = 0, and cos x = 1. Transformation process. There are 2 main approaches to solve a trig function F(x). 1. Transform F(x) into a product of many basic trig functions.
