Simplifying 5y2 + -10y + 35 = 0 Reorder the terms: 35 + -10y + 5y2 = 0 Solving 35 + -10y + 5y2 = 0 Solving for variable 'y'. Factor out the Greatest Common Factor (GCF), '5'. 5(7 + -2y + y2) = 0 Ignore the factor 5.Subproblem 1
Set the factor '(7 + -2y + y2)' equal to zero and attempt to solve: Simplifying 7 + -2y + y2 = 0 Solving 7 + -2y + y2 = 0 Begin completing the square. Move the constant term to the right: Add '-7' to each side of the equation. 7 + -2y + -7 + y2 = 0 + -7 Reorder the terms: 7 + -7 + -2y + y2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -2y + y2 = 0 + -7 -2y + y2 = 0 + -7 Combine like terms: 0 + -7 = -7 -2y + y2 = -7 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 = -7 + 1 Reorder the terms: 1 + -2y + y2 = -7 + 1 Combine like terms: -7 + 1 = -6 1 + -2y + y2 = -6 Factor a perfect square on the left side: (y + -1)(y + -1) = -6 Can't calculate square root of the right side.
