Simplifying 6y2 + 7y = 9y + -3 Reorder the terms: 7y + 6y2 = 9y + -3 Reorder the terms: 7y + 6y2 = -3 + 9y Solving 7y + 6y2 = -3 + 9y Solving for variable 'y'. Reorder the terms: 3 + 7y + -9y + 6y2 = -3 + 9y + 3 + -9y Combine like terms: 7y + -9y = -2y 3 + -2y + 6y2 = -3 + 9y + 3 + -9y Reorder the terms: 3 + -2y + 6y2 = -3 + 3 + 9y + -9y Combine like terms: -3 + 3 = 0 3 + -2y + 6y2 = 0 + 9y + -9y 3 + -2y + 6y2 = 9y + -9y Combine like terms: 9y + -9y = 0 3 + -2y + 6y2 = 0 Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. 0.5 + -0.3333333333y + y2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -0.3333333333y + -0.5 + y2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -0.3333333333y + y2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -0.3333333333y + y2 = 0 + -0.5 -0.3333333333y + y2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -0.3333333333y + y2 = -0.5 The y term is -0.3333333333y. Take half its coefficient (-0.1666666667). Square it (0.02777777779) and add it to both sides. Add '0.02777777779' to each side of the equation. -0.3333333333y + 0.02777777779 + y2 = -0.5 + 0.02777777779 Reorder the terms: 0.02777777779 + -0.3333333333y + y2 = -0.5 + 0.02777777779 Combine like terms: -0.5 + 0.02777777779 = -0.47222222221 0.02777777779 + -0.3333333333y + y2 = -0.47222222221 Factor a perfect square on the left side: (y + -0.1666666667)(y + -0.1666666667) = -0.47222222221 Can't calculate square root of the right side. The solution to this equation could not be determined.
