Simplifying f(2x + 3) = (x + -3)(x + 3) Reorder the terms: f(3 + 2x) = (x + -3)(x + 3) (3 * f + 2x * f) = (x + -3)(x + 3) (3f + 2fx) = (x + -3)(x + 3) Reorder the terms: 3f + 2fx = (-3 + x)(x + 3) Reorder the terms: 3f + 2fx = (-3 + x)(3 + x) Multiply (-3 + x) * (3 + x) 3f + 2fx = (-3(3 + x) + x(3 + x)) 3f + 2fx = ((3 * -3 + x * -3) + x(3 + x)) 3f + 2fx = ((-9 + -3x) + x(3 + x)) 3f + 2fx = (-9 + -3x + (3 * x + x * x)) 3f + 2fx = (-9 + -3x + (3x + x2)) Combine like terms: -3x + 3x = 0 3f + 2fx = (-9 + 0 + x2) 3f + 2fx = (-9 + x2) Solving 3f + 2fx = -9 + x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Reorder the terms: 9 + 3f + 2fx + -1x2 = -9 + x2 + 9 + -1x2 Reorder the terms: 9 + 3f + 2fx + -1x2 = -9 + 9 + x2 + -1x2 Combine like terms: -9 + 9 = 0 9 + 3f + 2fx + -1x2 = 0 + x2 + -1x2 9 + 3f + 2fx + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 9 + 3f + 2fx + -1x2 = 0 The solution to this equation could not be determined.
