Simplifying 5y2 + 40y + -4 = 0 Reorder the terms: -4 + 40y + 5y2 = 0 Solving -4 + 40y + 5y2 = 0 Solving for variable 'y'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -0.8 + 8y + y2 = 0 Move the constant term to the right: Add '0.8' to each side of the equation. -0.8 + 8y + 0.8 + y2 = 0 + 0.8 Reorder the terms: -0.8 + 0.8 + 8y + y2 = 0 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + 8y + y2 = 0 + 0.8 8y + y2 = 0 + 0.8 Combine like terms: 0 + 0.8 = 0.8 8y + y2 = 0.8 The y term is 8y. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8y + 16 + y2 = 0.8 + 16 Reorder the terms: 16 + 8y + y2 = 0.8 + 16 Combine like terms: 0.8 + 16 = 16.8 16 + 8y + y2 = 16.8 Factor a perfect square on the left side: (y + 4)(y + 4) = 16.8 Calculate the square root of the right side: 4.098780306 Break this problem into two subproblems by setting (y + 4) equal to 4.098780306 and -4.098780306.Subproblem 1
y + 4 = 4.098780306 Simplifying y + 4 = 4.098780306 Reorder the terms: 4 + y = 4.098780306 Solving 4 + y = 4.098780306 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + y = 4.098780306 + -4 Combine like terms: 4 + -4 = 0 0 + y = 4.098780306 + -4 y = 4.098780306 + -4 Combine like terms: 4.098780306 + -4 = 0.098780306 y = 0.098780306 Simplifying y = 0.098780306Subproblem 2
y + 4 = -4.098780306 Simplifying y + 4 = -4.098780306 Reorder the terms: 4 + y = -4.098780306 Solving 4 + y = -4.098780306 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + y = -4.098780306 + -4 Combine like terms: 4 + -4 = 0 0 + y = -4.098780306 + -4 y = -4.098780306 + -4 Combine like terms: -4.098780306 + -4 = -8.098780306 y = -8.098780306 Simplifying y = -8.098780306Solution
The solution to the problem is based on the solutions from the subproblems. y = {0.098780306, -8.098780306}
