Simplifying 10y2 + -15y + -7 = 0 Reorder the terms: -7 + -15y + 10y2 = 0 Solving -7 + -15y + 10y2 = 0 Solving for variable 'y'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -0.7 + -1.5y + y2 = 0 Move the constant term to the right: Add '0.7' to each side of the equation. -0.7 + -1.5y + 0.7 + y2 = 0 + 0.7 Reorder the terms: -0.7 + 0.7 + -1.5y + y2 = 0 + 0.7 Combine like terms: -0.7 + 0.7 = 0.0 0.0 + -1.5y + y2 = 0 + 0.7 -1.5y + y2 = 0 + 0.7 Combine like terms: 0 + 0.7 = 0.7 -1.5y + y2 = 0.7 The y term is -1.5y. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5y + 0.5625 + y2 = 0.7 + 0.5625 Reorder the terms: 0.5625 + -1.5y + y2 = 0.7 + 0.5625 Combine like terms: 0.7 + 0.5625 = 1.2625 0.5625 + -1.5y + y2 = 1.2625 Factor a perfect square on the left side: (y + -0.75)(y + -0.75) = 1.2625 Calculate the square root of the right side: 1.123610253 Break this problem into two subproblems by setting (y + -0.75) equal to 1.123610253 and -1.123610253.Subproblem 1
y + -0.75 = 1.123610253 Simplifying y + -0.75 = 1.123610253 Reorder the terms: -0.75 + y = 1.123610253 Solving -0.75 + y = 1.123610253 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + y = 1.123610253 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + y = 1.123610253 + 0.75 y = 1.123610253 + 0.75 Combine like terms: 1.123610253 + 0.75 = 1.873610253 y = 1.873610253 Simplifying y = 1.873610253Subproblem 2
y + -0.75 = -1.123610253 Simplifying y + -0.75 = -1.123610253 Reorder the terms: -0.75 + y = -1.123610253 Solving -0.75 + y = -1.123610253 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + y = -1.123610253 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + y = -1.123610253 + 0.75 y = -1.123610253 + 0.75 Combine like terms: -1.123610253 + 0.75 = -0.373610253 y = -0.373610253 Simplifying y = -0.373610253Solution
