Reorder the terms: 6 + -10 + 4y + 2y + -7y2 + -5y2 = 10 + -2y + 5y2 + -10 + 2y + -5y2 Combine like terms: 6 + -10 = -4 -4 + 4y + 2y + -7y2 + -5y2 = 10 + -2y + 5y2 + -10 + 2y + -5y2 Combine like terms: 4y + 2y = 6y -4 + 6y + -7y2 + -5y2 = 10 + -2y + 5y2 + -10 + 2y + -5y2 Combine like terms: -7y2 + -5y2 = -12y2 -4 + 6y + -12y2 = 10 + -2y + 5y2 + -10 + 2y + -5y2 Reorder the terms: -4 + 6y + -12y2 = 10 + -10 + -2y + 2y + 5y2 + -5y2 Combine like terms: 10 + -10 = 0 -4 + 6y + -12y2 = 0 + -2y + 2y + 5y2 + -5y2 -4 + 6y + -12y2 = -2y + 2y + 5y2 + -5y2 Combine like terms: -2y + 2y = 0 -4 + 6y + -12y2 = 0 + 5y2 + -5y2 -4 + 6y + -12y2 = 5y2 + -5y2 Combine like terms: 5y2 + -5y2 = 0 -4 + 6y + -12y2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-2 + 3y + -6y2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-2 + 3y + -6y2)' equal to zero and attempt to solve: Simplifying -2 + 3y + -6y2 = 0 Solving -2 + 3y + -6y2 = 0 Begin completing the square. Divide all terms by -6 the coefficient of the squared term: Divide each side by '-6'. 0.3333333333 + -0.5y + y2 = 0 Move the constant term to the right: Add '-0.3333333333' to each side of the equation. 0.3333333333 + -0.5y + -0.3333333333 + y2 = 0 + -0.3333333333 Reorder the terms: 0.3333333333 + -0.3333333333 + -0.5y + y2 = 0 + -0.3333333333 Combine like terms: 0.3333333333 + -0.3333333333 = 0.0000000000 0.0000000000 + -0.5y + y2 = 0 + -0.3333333333 -0.5y + y2 = 0 + -0.3333333333 Combine like terms: 0 + -0.3333333333 = -0.3333333333 -0.5y + y2 = -0.3333333333 The y term is -0.5y. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5y + 0.0625 + y2 = -0.3333333333 + 0.0625 Reorder the terms: 0.0625 + -0.5y + y2 = -0.3333333333 + 0.0625 Combine like terms: -0.3333333333 + 0.0625 = -0.2708333333 0.0625 + -0.5y + y2 = -0.2708333333 Factor a perfect square on the left side: (y + -0.25)(y + -0.25) = -0.2708333333 Can't calculate square root of the right side.
