Simplifying x2a + (x + -4) = (x + 4) * a Reorder the terms: ax2 + (-4 + x) = (x + 4) * a Remove parenthesis around (-4 + x) ax2 + -4 + x = (x + 4) * a Reorder the terms: -4 + ax2 + x = (x + 4) * a Reorder the terms: -4 + ax2 + x = (4 + x) * a Reorder the terms for easier multiplication: -4 + ax2 + x = a(4 + x) -4 + ax2 + x = (4 * a + x * a) -4 + ax2 + x = (4a + ax) Solving -4 + ax2 + x = 4a + ax Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-4a' to each side of the equation. -4 + ax2 + -4a + x = 4a + -4a + ax Reorder the terms: -4 + -4a + ax2 + x = 4a + -4a + ax Combine like terms: 4a + -4a = 0 -4 + -4a + ax2 + x = 0 + ax -4 + -4a + ax2 + x = ax Add '-1ax' to each side of the equation. -4 + -4a + ax2 + -1ax + x = ax + -1ax Reorder the terms: -4 + -4a + -1ax + ax2 + x = ax + -1ax Combine like terms: ax + -1ax = 0 -4 + -4a + -1ax + ax2 + x = 0 Add '4' to each side of the equation. -4 + -4a + -1ax + ax2 + 4 + x = 0 + 4 Reorder the terms: -4 + 4 + -4a + -1ax + ax2 + x = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -4a + -1ax + ax2 + x = 0 + 4 -4a + -1ax + ax2 + x = 0 + 4 Combine like terms: 0 + 4 = 4 -4a + -1ax + ax2 + x = 4 Add '-1x' to each side of the equation. -4a + -1ax + ax2 + x + -1x = 4 + -1x Combine like terms: x + -1x = 0 -4a + -1ax + ax2 + 0 = 4 + -1x -4a + -1ax + ax2 = 4 + -1x Reorder the terms: -4 + -4a + -1ax + ax2 + x = 4 + -1x + -4 + x Reorder the terms: -4 + -4a + -1ax + ax2 + x = 4 + -4 + -1x + x Combine like terms: 4 + -4 = 0 -4 + -4a + -1ax + ax2 + x = 0 + -1x + x -4 + -4a + -1ax + ax2 + x = -1x + x Combine like terms: -1x + x = 0 -4 + -4a + -1ax + ax2 + x = 0 The solution to this equation could not be determined.
