Simplifying x2 + 19x + 150 = 180 Reorder the terms: 150 + 19x + x2 = 180 Solving 150 + 19x + x2 = 180 Solving for variable 'x'. Reorder the terms: 150 + -180 + 19x + x2 = 180 + -180 Combine like terms: 150 + -180 = -30 -30 + 19x + x2 = 180 + -180 Combine like terms: 180 + -180 = 0 -30 + 19x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '30' to each side of the equation. -30 + 19x + 30 + x2 = 0 + 30 Reorder the terms: -30 + 30 + 19x + x2 = 0 + 30 Combine like terms: -30 + 30 = 0 0 + 19x + x2 = 0 + 30 19x + x2 = 0 + 30 Combine like terms: 0 + 30 = 30 19x + x2 = 30 The x term is 19x. Take half its coefficient (9.5). Square it (90.25) and add it to both sides. Add '90.25' to each side of the equation. 19x + 90.25 + x2 = 30 + 90.25 Reorder the terms: 90.25 + 19x + x2 = 30 + 90.25 Combine like terms: 30 + 90.25 = 120.25 90.25 + 19x + x2 = 120.25 Factor a perfect square on the left side: (x + 9.5)(x + 9.5) = 120.25 Calculate the square root of the right side: 10.9658561 Break this problem into two subproblems by setting (x + 9.5) equal to 10.9658561 and -10.9658561.Subproblem 1
x + 9.5 = 10.9658561 Simplifying x + 9.5 = 10.9658561 Reorder the terms: 9.5 + x = 10.9658561 Solving 9.5 + x = 10.9658561 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9.5' to each side of the equation. 9.5 + -9.5 + x = 10.9658561 + -9.5 Combine like terms: 9.5 + -9.5 = 0.0 0.0 + x = 10.9658561 + -9.5 x = 10.9658561 + -9.5 Combine like terms: 10.9658561 + -9.5 = 1.4658561 x = 1.4658561 Simplifying x = 1.4658561Subproblem 2
x + 9.5 = -10.9658561 Simplifying x + 9.5 = -10.9658561 Reorder the terms: 9.5 + x = -10.9658561 Solving 9.5 + x = -10.9658561 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9.5' to each side of the equation. 9.5 + -9.5 + x = -10.9658561 + -9.5 Combine like terms: 9.5 + -9.5 = 0.0 0.0 + x = -10.9658561 + -9.5 x = -10.9658561 + -9.5 Combine like terms: -10.9658561 + -9.5 = -20.4658561 x = -20.4658561 Simplifying x = -20.4658561Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.4658561, -20.4658561}
