Simplifying 0 = 2y2 + 5y + 7 Reorder the terms: 0 = 7 + 5y + 2y2 Solving 0 = 7 + 5y + 2y2 Solving for variable 'y'. Combine like terms: 0 + -7 = -7 -7 + -5y + -2y2 = 7 + 5y + 2y2 + -7 + -5y + -2y2 Reorder the terms: -7 + -5y + -2y2 = 7 + -7 + 5y + -5y + 2y2 + -2y2 Combine like terms: 7 + -7 = 0 -7 + -5y + -2y2 = 0 + 5y + -5y + 2y2 + -2y2 -7 + -5y + -2y2 = 5y + -5y + 2y2 + -2y2 Combine like terms: 5y + -5y = 0 -7 + -5y + -2y2 = 0 + 2y2 + -2y2 -7 + -5y + -2y2 = 2y2 + -2y2 Combine like terms: 2y2 + -2y2 = 0 -7 + -5y + -2y2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(7 + 5y + 2y2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(7 + 5y + 2y2)' equal to zero and attempt to solve: Simplifying 7 + 5y + 2y2 = 0 Solving 7 + 5y + 2y2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 3.5 + 2.5y + y2 = 0 Move the constant term to the right: Add '-3.5' to each side of the equation. 3.5 + 2.5y + -3.5 + y2 = 0 + -3.5 Reorder the terms: 3.5 + -3.5 + 2.5y + y2 = 0 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + 2.5y + y2 = 0 + -3.5 2.5y + y2 = 0 + -3.5 Combine like terms: 0 + -3.5 = -3.5 2.5y + y2 = -3.5 The y term is 2.5y. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5y + 1.5625 + y2 = -3.5 + 1.5625 Reorder the terms: 1.5625 + 2.5y + y2 = -3.5 + 1.5625 Combine like terms: -3.5 + 1.5625 = -1.9375 1.5625 + 2.5y + y2 = -1.9375 Factor a perfect square on the left side: (y + 1.25)(y + 1.25) = -1.9375 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
