Simplifying 3x + -30 * 150 + -1x * 2x = 0 Multiply -30 * 150 3x + -4500 + -1x * 2x = 0 Reorder the terms for easier multiplication: 3x + -4500 + -1 * 2x * x = 0 Multiply -1 * 2 3x + -4500 + -2x * x = 0 Multiply x * x 3x + -4500 + -2x2 = 0 Reorder the terms: -4500 + 3x + -2x2 = 0 Solving -4500 + 3x + -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'. 2250 + -1.5x + x2 = 0 Move the constant term to the right: Add '-2250' to each side of the equation. 2250 + -1.5x + -2250 + x2 = 0 + -2250 Reorder the terms: 2250 + -2250 + -1.5x + x2 = 0 + -2250 Combine like terms: 2250 + -2250 = 0 0 + -1.5x + x2 = 0 + -2250 -1.5x + x2 = 0 + -2250 Combine like terms: 0 + -2250 = -2250 -1.5x + x2 = -2250 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = -2250 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = -2250 + 0.5625 Combine like terms: -2250 + 0.5625 = -2249.4375 0.5625 + -1.5x + x2 = -2249.4375 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = -2249.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
