-6x^{2}-2x+1=0 . Quadratic equations such as this one can be solved by completing the square. In order to complete the square, the equation must first be in the form x^{2}+bx=c.-6x^{2}-2x+1-1=-1 . Subtract 1 from both sides of the equation.-6x^{2}-2x=-1 . Subtracting 1 from itself leaves 0.3.2 Solving 3x2-6x+1 = 0 by Completing The Square . Divide both sides of the equation by 3 to have 1 as the coefficient of the first term : x2-2x+ (1/3) = 0. Subtract 1/3 from both side of the equation : x2-2x = -1/3. Now the clever bit: Take the coefficient of x , which is 2 , divide by two, giving 1 , and finally square it giving 1.2x2+6x+3 = 0 Divide both sides of the equation by 2 to have 1 as the coefficient of the first term : x2+3x+ (3/2) = 0. Subtract 3/2 from both side of the equation : x2+3x = -3/2. Now the clever bit: Take the coefficient of x , which is 3 , divide by two, giving 3/2 , and finally square it giving 9/4. Add 9/4 to both sides of the equation :Divide \frac{6}{5}, the coefficient of the x term, by 2 to get \frac{3}{5}. Then add the square of \frac{3}{5} to both sides of the equation. This step makes the left hand side of the equation a perfect square. Equation at the end of step 1 (2x2 - 6x) - 1 = 0 . STEP. 2: Trying to factor by splitting the middle term. 2.1 Factoring 2x2-6x-1 . The first term is, 2x2 its coefficient is 2 . The middle term is, -6x its coefficient is -6 . The last term, "the constant", is -1 . Step-1 : Multiply the coefficient of the first term by the constant 2 • -1 = -2Factor 6x^2-x-1. 6x2 − x − 1 6 x 2 - x - 1.
