Simplifying 0 = x2 + -3x + -1.5 Reorder the terms: 0 = -1.5 + -3x + x2 Solving 0 = -1.5 + -3x + x2 Solving for variable 'x'. Combine like terms: 0 + 1.5 = 1.5 1.5 + 3x + -1x2 = -1.5 + -3x + x2 + 1.5 + 3x + -1x2 Reorder the terms: 1.5 + 3x + -1x2 = -1.5 + 1.5 + -3x + 3x + x2 + -1x2 Combine like terms: -1.5 + 1.5 = 0.0 1.5 + 3x + -1x2 = 0.0 + -3x + 3x + x2 + -1x2 1.5 + 3x + -1x2 = -3x + 3x + x2 + -1x2 Combine like terms: -3x + 3x = 0 1.5 + 3x + -1x2 = 0 + x2 + -1x2 1.5 + 3x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 1.5 + 3x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -1.5 + -3x + x2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + -3x + 1.5 + x2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + -3x + x2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + -3x + x2 = 0 + 1.5 -3x + x2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 -3x + x2 = 1.5 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 = 1.5 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 1.5 + 2.25 Combine like terms: 1.5 + 2.25 = 3.75 2.25 + -3x + x2 = 3.75 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 3.75 Calculate the square root of the right side: 1.936491673 Break this problem into two subproblems by setting (x + -1.5) equal to 1.936491673 and -1.936491673.Subproblem 1
x + -1.5 = 1.936491673 Simplifying x + -1.5 = 1.936491673 Reorder the terms: -1.5 + x = 1.936491673 Solving -1.5 + x = 1.936491673 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 = 1.936491673 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 1.936491673 + 1.5 x = 1.936491673 + 1.5 Combine like terms: 1.936491673 + 1.5 = 3.436491673 x = 3.436491673 Simplifying x = 3.436491673Subproblem 2
x + -1.5 = -1.936491673 Simplifying x + -1.5 = -1.936491673 Reorder the terms: -1.5 + x = -1.936491673 Solving -1.5 + x = -1.936491673 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 = -1.936491673 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -1.936491673 + 1.5 x = -1.936491673 + 1.5 Combine like terms: -1.936491673 + 1.5 = -0.436491673 x = -0.436491673 Simplifying x = -0.436491673Solution
