Simplifying 25x2 + -70x = 49 Reorder the terms: -70x + 25x2 = 49 Solving -70x + 25x2 = 49 Solving for variable 'x'. Reorder the terms: -49 + -70x + 25x2 = 49 + -49 Combine like terms: 49 + -49 = 0 -49 + -70x + 25x2 = 0 Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. -1.96 + -2.8x + x2 = 0 Move the constant term to the right: Add '1.96' to each side of the equation. -1.96 + -2.8x + 1.96 + x2 = 0 + 1.96 Reorder the terms: -1.96 + 1.96 + -2.8x + x2 = 0 + 1.96 Combine like terms: -1.96 + 1.96 = 0.00 0.00 + -2.8x + x2 = 0 + 1.96 -2.8x + x2 = 0 + 1.96 Combine like terms: 0 + 1.96 = 1.96 -2.8x + x2 = 1.96 The x term is -2.8x. Take half its coefficient (-1.4). Square it (1.96) and add it to both sides. Add '1.96' to each side of the equation. -2.8x + 1.96 + x2 = 1.96 + 1.96 Reorder the terms: 1.96 + -2.8x + x2 = 1.96 + 1.96 Combine like terms: 1.96 + 1.96 = 3.92 1.96 + -2.8x + x2 = 3.92 Factor a perfect square on the left side: (x + -1.4)(x + -1.4) = 3.92 Calculate the square root of the right side: 1.979898987 Break this problem into two subproblems by setting (x + -1.4) equal to 1.979898987 and -1.979898987.Subproblem 1
x + -1.4 = 1.979898987 Simplifying x + -1.4 = 1.979898987 Reorder the terms: -1.4 + x = 1.979898987 Solving -1.4 + x = 1.979898987 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.4' to each side of the equation. -1.4 + 1.4 + x = 1.979898987 + 1.4 Combine like terms: -1.4 + 1.4 = 0.0 0.0 + x = 1.979898987 + 1.4 x = 1.979898987 + 1.4 Combine like terms: 1.979898987 + 1.4 = 3.379898987 x = 3.379898987 Simplifying x = 3.379898987Subproblem 2
x + -1.4 = -1.979898987 Simplifying x + -1.4 = -1.979898987 Reorder the terms: -1.4 + x = -1.979898987 Solving -1.4 + x = -1.979898987 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.4' to each side of the equation. -1.4 + 1.4 + x = -1.979898987 + 1.4 Combine like terms: -1.4 + 1.4 = 0.0 0.0 + x = -1.979898987 + 1.4 x = -1.979898987 + 1.4 Combine like terms: -1.979898987 + 1.4 = -0.579898987 x = -0.579898987 Simplifying x = -0.579898987Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.379898987, -0.579898987}
