Simplifying 1.44 = x2 + 70x Reorder the terms: 1.44 = 70x + x2 Solving 1.44 = 70x + x2 Solving for variable 'x'. Reorder the terms: 1.44 + -70x + -1x2 = 70x + -70x + x2 + -1x2 Combine like terms: 70x + -70x = 0 1.44 + -70x + -1x2 = 0 + x2 + -1x2 1.44 + -70x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 1.44 + -70x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -1.44 + 70x + x2 = 0 Move the constant term to the right: Add '1.44' to each side of the equation. -1.44 + 70x + 1.44 + x2 = 0 + 1.44 Reorder the terms: -1.44 + 1.44 + 70x + x2 = 0 + 1.44 Combine like terms: -1.44 + 1.44 = 0.00 0.00 + 70x + x2 = 0 + 1.44 70x + x2 = 0 + 1.44 Combine like terms: 0 + 1.44 = 1.44 70x + x2 = 1.44 The x term is 70x. Take half its coefficient (35). Square it (1225) and add it to both sides. Add '1225' to each side of the equation. 70x + 1225 + x2 = 1.44 + 1225 Reorder the terms: 1225 + 70x + x2 = 1.44 + 1225 Combine like terms: 1.44 + 1225 = 1226.44 1225 + 70x + x2 = 1226.44 Factor a perfect square on the left side: (x + 35)(x + 35) = 1226.44 Calculate the square root of the right side: 35.020565387 Break this problem into two subproblems by setting (x + 35) equal to 35.020565387 and -35.020565387.Subproblem 1
x + 35 = 35.020565387 Simplifying x + 35 = 35.020565387 Reorder the terms: 35 + x = 35.020565387 Solving 35 + x = 35.020565387 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-35' to each side of the equation. 35 + -35 + x = 35.020565387 + -35 Combine like terms: 35 + -35 = 0 0 + x = 35.020565387 + -35 x = 35.020565387 + -35 Combine like terms: 35.020565387 + -35 = 0.020565387 x = 0.020565387 Simplifying x = 0.020565387Subproblem 2
x + 35 = -35.020565387 Simplifying x + 35 = -35.020565387 Reorder the terms: 35 + x = -35.020565387 Solving 35 + x = -35.020565387 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-35' to each side of the equation. 35 + -35 + x = -35.020565387 + -35 Combine like terms: 35 + -35 = 0 0 + x = -35.020565387 + -35 x = -35.020565387 + -35 Combine like terms: -35.020565387 + -35 = -70.020565387 x = -70.020565387 Simplifying x = -70.020565387Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.020565387, -70.020565387}
