Simplifying 2x2 + -60x + -45 = 0 Reorder the terms: -45 + -60x + 2x2 = 0 Solving -45 + -60x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -22.5 + -30x + x2 = 0 Move the constant term to the right: Add '22.5' to each side of the equation. -22.5 + -30x + 22.5 + x2 = 0 + 22.5 Reorder the terms: -22.5 + 22.5 + -30x + x2 = 0 + 22.5 Combine like terms: -22.5 + 22.5 = 0.0 0.0 + -30x + x2 = 0 + 22.5 -30x + x2 = 0 + 22.5 Combine like terms: 0 + 22.5 = 22.5 -30x + x2 = 22.5 The x term is -30x. Take half its coefficient (-15). Square it (225) and add it to both sides. Add '225' to each side of the equation. -30x + 225 + x2 = 22.5 + 225 Reorder the terms: 225 + -30x + x2 = 22.5 + 225 Combine like terms: 22.5 + 225 = 247.5 225 + -30x + x2 = 247.5 Factor a perfect square on the left side: (x + -15)(x + -15) = 247.5 Calculate the square root of the right side: 15.732132723 Break this problem into two subproblems by setting (x + -15) equal to 15.732132723 and -15.732132723.Subproblem 1
x + -15 = 15.732132723 Simplifying x + -15 = 15.732132723 Reorder the terms: -15 + x = 15.732132723 Solving -15 + x = 15.732132723 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '15' to each side of the equation. -15 + 15 + x = 15.732132723 + 15 Combine like terms: -15 + 15 = 0 0 + x = 15.732132723 + 15 x = 15.732132723 + 15 Combine like terms: 15.732132723 + 15 = 30.732132723 x = 30.732132723 Simplifying x = 30.732132723Subproblem 2
x + -15 = -15.732132723 Simplifying x + -15 = -15.732132723 Reorder the terms: -15 + x = -15.732132723 Solving -15 + x = -15.732132723 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '15' to each side of the equation. -15 + 15 + x = -15.732132723 + 15 Combine like terms: -15 + 15 = 0 0 + x = -15.732132723 + 15 x = -15.732132723 + 15 Combine like terms: -15.732132723 + 15 = -0.732132723 x = -0.732132723 Simplifying x = -0.732132723Solution
