Simplifying F(x + 7) = x2 + 9x + -9 Reorder the terms: F(7 + x) = x2 + 9x + -9 (7 * F + x * F) = x2 + 9x + -9 (7F + xF) = x2 + 9x + -9 Reorder the terms: 7F + xF = -9 + 9x + x2 Solving 7F + xF = -9 + 9x + x2 Solving for variable 'F'. Move all terms containing F to the left, all other terms to the right. Reorder the terms: 9 + 7F + -9x + xF + -1x2 = -9 + 9x + x2 + 9 + -9x + -1x2 Reorder the terms: 9 + 7F + -9x + xF + -1x2 = -9 + 9 + 9x + -9x + x2 + -1x2 Combine like terms: -9 + 9 = 0 9 + 7F + -9x + xF + -1x2 = 0 + 9x + -9x + x2 + -1x2 9 + 7F + -9x + xF + -1x2 = 9x + -9x + x2 + -1x2 Combine like terms: 9x + -9x = 0 9 + 7F + -9x + xF + -1x2 = 0 + x2 + -1x2 9 + 7F + -9x + xF + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 9 + 7F + -9x + xF + -1x2 = 0 The solution to this equation could not be determined.
