Simplifying 25x2 + 80x + 62 = 0 Reorder the terms: 62 + 80x + 25x2 = 0 Solving 62 + 80x + 25x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. 2.48 + 3.2x + x2 = 0 Move the constant term to the right: Add '-2.48' to each side of the equation. 2.48 + 3.2x + -2.48 + x2 = 0 + -2.48 Reorder the terms: 2.48 + -2.48 + 3.2x + x2 = 0 + -2.48 Combine like terms: 2.48 + -2.48 = 0.00 0.00 + 3.2x + x2 = 0 + -2.48 3.2x + x2 = 0 + -2.48 Combine like terms: 0 + -2.48 = -2.48 3.2x + x2 = -2.48 The x term is 3.2x. Take half its coefficient (1.6). Square it (2.56) and add it to both sides. Add '2.56' to each side of the equation. 3.2x + 2.56 + x2 = -2.48 + 2.56 Reorder the terms: 2.56 + 3.2x + x2 = -2.48 + 2.56 Combine like terms: -2.48 + 2.56 = 0.08 2.56 + 3.2x + x2 = 0.08 Factor a perfect square on the left side: (x + 1.6)(x + 1.6) = 0.08 Calculate the square root of the right side: 0.282842712 Break this problem into two subproblems by setting (x + 1.6) equal to 0.282842712 and -0.282842712.Subproblem 1
x + 1.6 = 0.282842712 Simplifying x + 1.6 = 0.282842712 Reorder the terms: 1.6 + x = 0.282842712 Solving 1.6 + x = 0.282842712 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.6' to each side of the equation. 1.6 + -1.6 + x = 0.282842712 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + x = 0.282842712 + -1.6 x = 0.282842712 + -1.6 Combine like terms: 0.282842712 + -1.6 = -1.317157288 x = -1.317157288 Simplifying x = -1.317157288Subproblem 2
x + 1.6 = -0.282842712 Simplifying x + 1.6 = -0.282842712 Reorder the terms: 1.6 + x = -0.282842712 Solving 1.6 + x = -0.282842712 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.6' to each side of the equation. 1.6 + -1.6 + x = -0.282842712 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + x = -0.282842712 + -1.6 x = -0.282842712 + -1.6 Combine like terms: -0.282842712 + -1.6 = -1.882842712 x = -1.882842712 Simplifying x = -1.882842712Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.317157288, -1.882842712}
