Simplifying -6y2 + -4y = -6 Reorder the terms: -4y + -6y2 = -6 Solving -4y + -6y2 = -6 Solving for variable 'y'. Reorder the terms: 6 + -4y + -6y2 = -6 + 6 Combine like terms: -6 + 6 = 0 6 + -4y + -6y2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(3 + -2y + -3y2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(3 + -2y + -3y2)' equal to zero and attempt to solve: Simplifying 3 + -2y + -3y2 = 0 Solving 3 + -2y + -3y2 = 0 Begin completing the square. Divide all terms by -3 the coefficient of the squared term: Divide each side by '-3'. -1 + 0.6666666667y + y2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + 0.6666666667y + 1 + y2 = 0 + 1 Reorder the terms: -1 + 1 + 0.6666666667y + y2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 0.6666666667y + y2 = 0 + 1 0.6666666667y + y2 = 0 + 1 Combine like terms: 0 + 1 = 1 0.6666666667y + y2 = 1 The y term is 0.6666666667y. Take half its coefficient (0.3333333334). Square it (0.1111111112) and add it to both sides. Add '0.1111111112' to each side of the equation. 0.6666666667y + 0.1111111112 + y2 = 1 + 0.1111111112 Reorder the terms: 0.1111111112 + 0.6666666667y + y2 = 1 + 0.1111111112 Combine like terms: 1 + 0.1111111112 = 1.1111111112 0.1111111112 + 0.6666666667y + y2 = 1.1111111112 Factor a perfect square on the left side: (y + 0.3333333334)(y + 0.3333333334) = 1.1111111112 Calculate the square root of the right side: 1.054092553 Break this problem into two subproblems by setting (y + 0.3333333334) equal to 1.054092553 and -1.054092553.Subproblem 1
