Simplifying 2y2 + -4y = -40 Reorder the terms: -4y + 2y2 = -40 Solving -4y + 2y2 = -40 Solving for variable 'y'. Reorder the terms: 40 + -4y + 2y2 = -40 + 40 Combine like terms: -40 + 40 = 0 40 + -4y + 2y2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(20 + -2y + y2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(20 + -2y + y2)' equal to zero and attempt to solve: Simplifying 20 + -2y + y2 = 0 Solving 20 + -2y + y2 = 0 Begin completing the square. Move the constant term to the right: Add '-20' to each side of the equation. 20 + -2y + -20 + y2 = 0 + -20 Reorder the terms: 20 + -20 + -2y + y2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + -2y + y2 = 0 + -20 -2y + y2 = 0 + -20 Combine like terms: 0 + -20 = -20 -2y + y2 = -20 The y term is -2y. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2y + 1 + y2 = -20 + 1 Reorder the terms: 1 + -2y + y2 = -20 + 1 Combine like terms: -20 + 1 = -19 1 + -2y + y2 = -19 Factor a perfect square on the left side: (y + -1)(y + -1) = -19 Can't calculate square root of the right side.
