Simplifying 2x2 + 14x + -49 = x2 + 16x + -64 Reorder the terms: -49 + 14x + 2x2 = x2 + 16x + -64 Reorder the terms: -49 + 14x + 2x2 = -64 + 16x + x2 Solving -49 + 14x + 2x2 = -64 + 16x + x2 Solving for variable 'x'. Reorder the terms: -49 + 64 + 14x + -16x + 2x2 + -1x2 = -64 + 16x + x2 + 64 + -16x + -1x2 Combine like terms: -49 + 64 = 15 15 + 14x + -16x + 2x2 + -1x2 = -64 + 16x + x2 + 64 + -16x + -1x2 Combine like terms: 14x + -16x = -2x 15 + -2x + 2x2 + -1x2 = -64 + 16x + x2 + 64 + -16x + -1x2 Combine like terms: 2x2 + -1x2 = 1x2 15 + -2x + 1x2 = -64 + 16x + x2 + 64 + -16x + -1x2 Reorder the terms: 15 + -2x + 1x2 = -64 + 64 + 16x + -16x + x2 + -1x2 Combine like terms: -64 + 64 = 0 15 + -2x + 1x2 = 0 + 16x + -16x + x2 + -1x2 15 + -2x + 1x2 = 16x + -16x + x2 + -1x2 Combine like terms: 16x + -16x = 0 15 + -2x + 1x2 = 0 + x2 + -1x2 15 + -2x + 1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 15 + -2x + 1x2 = 0 Begin completing the square. Move the constant term to the right: Add '-15' to each side of the equation. 15 + -2x + -15 + x2 = 0 + -15 Reorder the terms: 15 + -15 + -2x + x2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + -2x + x2 = 0 + -15 -2x + x2 = 0 + -15 Combine like terms: 0 + -15 = -15 -2x + x2 = -15 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = -15 + 1 Reorder the terms: 1 + -2x + x2 = -15 + 1 Combine like terms: -15 + 1 = -14 1 + -2x + x2 = -14 Factor a perfect square on the left side: (x + -1)(x + -1) = -14 Can't calculate square root of the right side. The solution to this equation could not be determined.
