Simplifying 2y4 + -7y2 + 1 = 0 Reorder the terms: 1 + -7y2 + 2y4 = 0 Solving 1 + -7y2 + 2y4 = 0 Solving for variable 'y'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 0.5 + -3.5y2 + y4 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -3.5y2 + -0.5 + y4 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -3.5y2 + y4 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -3.5y2 + y4 = 0 + -0.5 -3.5y2 + y4 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -3.5y2 + y4 = -0.5 The y term is -3.5y2. Take half its coefficient (-1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. -3.5y2 + 3.0625 + y4 = -0.5 + 3.0625 Reorder the terms: 3.0625 + -3.5y2 + y4 = -0.5 + 3.0625 Combine like terms: -0.5 + 3.0625 = 2.5625 3.0625 + -3.5y2 + y4 = 2.5625 Factor a perfect square on the left side: (y2 + -1.75)(y2 + -1.75) = 2.5625 Calculate the square root of the right side: 1.600781059 Break this problem into two subproblems by setting (y2 + -1.75) equal to 1.600781059 and -1.600781059.Subproblem 1
y2 + -1.75 = 1.600781059 Simplifying y2 + -1.75 = 1.600781059 Reorder the terms: -1.75 + y2 = 1.600781059 Solving -1.75 + y2 = 1.600781059 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '1.75' to each side of the equation. -1.75 + 1.75 + y2 = 1.600781059 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + y2 = 1.600781059 + 1.75 y2 = 1.600781059 + 1.75 Combine like terms: 1.600781059 + 1.75 = 3.350781059 y2 = 3.350781059 Simplifying y2 = 3.350781059 Take the square root of each side: y = {-1.830513878, 1.830513878}Subproblem 2
y2 + -1.75 = -1.600781059 Simplifying y2 + -1.75 = -1.600781059 Reorder the terms: -1.75 + y2 = -1.600781059 Solving -1.75 + y2 = -1.600781059 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '1.75' to each side of the equation. -1.75 + 1.75 + y2 = -1.600781059 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + y2 = -1.600781059 + 1.75 y2 = -1.600781059 + 1.75 Combine like terms: -1.600781059 + 1.75 = 0.149218941 y2 = 0.149218941 Simplifying y2 = 0.149218941 Take the square root of each side: y = {-0.386288676, 0.386288676}Solution
The solution to the problem is based on the solutions from the subproblems. y = {-1.830513878, 1.830513878, -0.386288676, 0.386288676}
