Simplifying -0.008x2 + 1.2x + 200 = 0 Reorder the terms: 200 + 1.2x + -0.008x2 = 0 Solving 200 + 1.2x + -0.008x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -0.008 the coefficient of the squared term: Divide each side by '-0.008'. -25000 + -150x + x2 = 0 Move the constant term to the right: Add '25000' to each side of the equation. -25000 + -150x + 25000 + x2 = 0 + 25000 Reorder the terms: -25000 + 25000 + -150x + x2 = 0 + 25000 Combine like terms: -25000 + 25000 = 0 0 + -150x + x2 = 0 + 25000 -150x + x2 = 0 + 25000 Combine like terms: 0 + 25000 = 25000 -150x + x2 = 25000 The x term is -150x. Take half its coefficient (-75). Square it (5625) and add it to both sides. Add '5625' to each side of the equation. -150x + 5625 + x2 = 25000 + 5625 Reorder the terms: 5625 + -150x + x2 = 25000 + 5625 Combine like terms: 25000 + 5625 = 30625 5625 + -150x + x2 = 30625 Factor a perfect square on the left side: (x + -75)(x + -75) = 30625 Calculate the square root of the right side: 175 Break this problem into two subproblems by setting (x + -75) equal to 175 and -175.Subproblem 1
x + -75 = 175 Simplifying x + -75 = 175 Reorder the terms: -75 + x = 175 Solving -75 + x = 175 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '75' to each side of the equation. -75 + 75 + x = 175 + 75 Combine like terms: -75 + 75 = 0 0 + x = 175 + 75 x = 175 + 75 Combine like terms: 175 + 75 = 250 x = 250 Simplifying x = 250Subproblem 2
x + -75 = -175 Simplifying x + -75 = -175 Reorder the terms: -75 + x = -175 Solving -75 + x = -175 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '75' to each side of the equation. -75 + 75 + x = -175 + 75 Combine like terms: -75 + 75 = 0 0 + x = -175 + 75 x = -175 + 75 Combine like terms: -175 + 75 = -100 x = -100 Simplifying x = -100Solution
The solution to the problem is based on the solutions from the subproblems. x = {250, -100}
