Simplifying 0 = -1x2 + 15x + -140 Reorder the terms: 0 = -140 + 15x + -1x2 Solving 0 = -140 + 15x + -1x2 Solving for variable 'x'. Combine like terms: 0 + 140 = 140 140 + -15x + x2 = -140 + 15x + -1x2 + 140 + -15x + x2 Reorder the terms: 140 + -15x + x2 = -140 + 140 + 15x + -15x + -1x2 + x2 Combine like terms: -140 + 140 = 0 140 + -15x + x2 = 0 + 15x + -15x + -1x2 + x2 140 + -15x + x2 = 15x + -15x + -1x2 + x2 Combine like terms: 15x + -15x = 0 140 + -15x + x2 = 0 + -1x2 + x2 140 + -15x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 140 + -15x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-140' to each side of the equation. 140 + -15x + -140 + x2 = 0 + -140 Reorder the terms: 140 + -140 + -15x + x2 = 0 + -140 Combine like terms: 140 + -140 = 0 0 + -15x + x2 = 0 + -140 -15x + x2 = 0 + -140 Combine like terms: 0 + -140 = -140 -15x + x2 = -140 The x term is -15x. Take half its coefficient (-7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. -15x + 56.25 + x2 = -140 + 56.25 Reorder the terms: 56.25 + -15x + x2 = -140 + 56.25 Combine like terms: -140 + 56.25 = -83.75 56.25 + -15x + x2 = -83.75 Factor a perfect square on the left side: (x + -7.5)(x + -7.5) = -83.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
