Simplifying x2 + 3x + -650 = 0 Reorder the terms: -650 + 3x + x2 = 0 Solving -650 + 3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '650' to each side of the equation. -650 + 3x + 650 + x2 = 0 + 650 Reorder the terms: -650 + 650 + 3x + x2 = 0 + 650 Combine like terms: -650 + 650 = 0 0 + 3x + x2 = 0 + 650 3x + x2 = 0 + 650 Combine like terms: 0 + 650 = 650 3x + x2 = 650 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 650 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 650 + 2.25 Combine like terms: 650 + 2.25 = 652.25 2.25 + 3x + x2 = 652.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 652.25 Calculate the square root of the right side: 25.539185578 Break this problem into two subproblems by setting (x + 1.5) equal to 25.539185578 and -25.539185578.Subproblem 1
x + 1.5 = 25.539185578 Simplifying x + 1.5 = 25.539185578 Reorder the terms: 1.5 + x = 25.539185578 Solving 1.5 + x = 25.539185578 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 25.539185578 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 25.539185578 + -1.5 x = 25.539185578 + -1.5 Combine like terms: 25.539185578 + -1.5 = 24.039185578 x = 24.039185578 Simplifying x = 24.039185578Subproblem 2
x + 1.5 = -25.539185578 Simplifying x + 1.5 = -25.539185578 Reorder the terms: 1.5 + x = -25.539185578 Solving 1.5 + x = -25.539185578 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -25.539185578 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -25.539185578 + -1.5 x = -25.539185578 + -1.5 Combine like terms: -25.539185578 + -1.5 = -27.039185578 x = -27.039185578 Simplifying x = -27.039185578Solution
