Simplifying 0.012x2 + 4.2x + -30 = 0 Reorder the terms: -30 + 4.2x + 0.012x2 = 0 Solving -30 + 4.2x + 0.012x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.012 the coefficient of the squared term: Divide each side by '0.012'. -2500 + 350x + x2 = 0 Move the constant term to the right: Add '2500' to each side of the equation. -2500 + 350x + 2500 + x2 = 0 + 2500 Reorder the terms: -2500 + 2500 + 350x + x2 = 0 + 2500 Combine like terms: -2500 + 2500 = 0 0 + 350x + x2 = 0 + 2500 350x + x2 = 0 + 2500 Combine like terms: 0 + 2500 = 2500 350x + x2 = 2500 The x term is 350x. Take half its coefficient (175). Square it (30625) and add it to both sides. Add '30625' to each side of the equation. 350x + 30625 + x2 = 2500 + 30625 Reorder the terms: 30625 + 350x + x2 = 2500 + 30625 Combine like terms: 2500 + 30625 = 33125 30625 + 350x + x2 = 33125 Factor a perfect square on the left side: (x + 175)(x + 175) = 33125 Calculate the square root of the right side: 182.002747232 Break this problem into two subproblems by setting (x + 175) equal to 182.002747232 and -182.002747232.Subproblem 1
x + 175 = 182.002747232 Simplifying x + 175 = 182.002747232 Reorder the terms: 175 + x = 182.002747232 Solving 175 + x = 182.002747232 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-175' to each side of the equation. 175 + -175 + x = 182.002747232 + -175 Combine like terms: 175 + -175 = 0 0 + x = 182.002747232 + -175 x = 182.002747232 + -175 Combine like terms: 182.002747232 + -175 = 7.002747232 x = 7.002747232 Simplifying x = 7.002747232Subproblem 2
x + 175 = -182.002747232 Simplifying x + 175 = -182.002747232 Reorder the terms: 175 + x = -182.002747232 Solving 175 + x = -182.002747232 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-175' to each side of the equation. 175 + -175 + x = -182.002747232 + -175 Combine like terms: 175 + -175 = 0 0 + x = -182.002747232 + -175 x = -182.002747232 + -175 Combine like terms: -182.002747232 + -175 = -357.002747232 x = -357.002747232 Simplifying x = -357.002747232Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.002747232, -357.002747232}
