Simplifying (a + 2) * x2 + 2x + -1a = 0 Reorder the terms: (2 + a) * x2 + 2x + -1a = 0 Reorder the terms for easier multiplication: x2(2 + a) + 2x + -1a = 0 (2 * x2 + a * x2) + 2x + -1a = 0 Reorder the terms: (ax2 + 2x2) + 2x + -1a = 0 (ax2 + 2x2) + 2x + -1a = 0 Reorder the terms: -1a + ax2 + 2x + 2x2 = 0 Solving -1a + ax2 + 2x + 2x2 = 0 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-2x' to each side of the equation. -1a + ax2 + 2x + -2x + 2x2 = 0 + -2x Combine like terms: 2x + -2x = 0 -1a + ax2 + 0 + 2x2 = 0 + -2x -1a + ax2 + 2x2 = 0 + -2x Remove the zero: -1a + ax2 + 2x2 = -2x Add '-2x2' to each side of the equation. -1a + ax2 + 2x2 + -2x2 = -2x + -2x2 Combine like terms: 2x2 + -2x2 = 0 -1a + ax2 + 0 = -2x + -2x2 -1a + ax2 = -2x + -2x2 Reorder the terms: -1a + ax2 + 2x + 2x2 = -2x + 2x + -2x2 + 2x2 Combine like terms: -2x + 2x = 0 -1a + ax2 + 2x + 2x2 = 0 + -2x2 + 2x2 -1a + ax2 + 2x + 2x2 = -2x2 + 2x2 Combine like terms: -2x2 + 2x2 = 0 -1a + ax2 + 2x + 2x2 = 0 The solution to this equation could not be determined.
