Simplifying 4 + -1(a2 + -2a + -9) = 9 + -1(2a + a2) Reorder the terms: 4 + -1(-9 + -2a + a2) = 9 + -1(2a + a2) 4 + (-9 * -1 + -2a * -1 + a2 * -1) = 9 + -1(2a + a2) 4 + (9 + 2a + -1a2) = 9 + -1(2a + a2) Combine like terms: 4 + 9 = 13 13 + 2a + -1a2 = 9 + -1(2a + a2) 13 + 2a + -1a2 = 9 + (2a * -1 + a2 * -1) 13 + 2a + -1a2 = 9 + (-2a + -1a2) Add 'a2' to each side of the equation. 13 + 2a + -1a2 + a2 = 9 + -2a + -1a2 + a2 Combine like terms: -1a2 + a2 = 0 13 + 2a + 0 = 9 + -2a + -1a2 + a2 13 + 2a = 9 + -2a + -1a2 + a2 Combine like terms: -1a2 + a2 = 0 13 + 2a = 9 + -2a + 0 13 + 2a = 9 + -2a Solving 13 + 2a = 9 + -2a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '2a' to each side of the equation. 13 + 2a + 2a = 9 + -2a + 2a Combine like terms: 2a + 2a = 4a 13 + 4a = 9 + -2a + 2a Combine like terms: -2a + 2a = 0 13 + 4a = 9 + 0 13 + 4a = 9 Add '-13' to each side of the equation. 13 + -13 + 4a = 9 + -13 Combine like terms: 13 + -13 = 0 0 + 4a = 9 + -13 4a = 9 + -13 Combine like terms: 9 + -13 = -4 4a = -4 Divide each side by '4'. a = -1 Simplifying a = -1
