Simplifying f(-4) * f(x) = x2 + -3x + 9 Reorder the terms for easier multiplication: -4f * f * x = x2 + -3x + 9 Multiply f * f -4f2 * x = x2 + -3x + 9 Multiply f2 * x -4f2x = x2 + -3x + 9 Reorder the terms: -4f2x = 9 + -3x + x2 Solving -4f2x = 9 + -3x + x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by '-4x'. f2 = -2.25x-1 + 0.75 + -0.25x Simplifying f2 = -2.25x-1 + 0.75 + -0.25x Reorder the terms: f2 = 0.75 + -2.25x-1 + -0.25x Reorder the terms: -0.75 + f2 + 2.25x-1 + 0.25x = 0.75 + -2.25x-1 + -0.25x + -0.75 + 2.25x-1 + 0.25x Reorder the terms: -0.75 + f2 + 2.25x-1 + 0.25x = 0.75 + -0.75 + -2.25x-1 + 2.25x-1 + -0.25x + 0.25x Combine like terms: 0.75 + -0.75 = 0.00 -0.75 + f2 + 2.25x-1 + 0.25x = 0.00 + -2.25x-1 + 2.25x-1 + -0.25x + 0.25x -0.75 + f2 + 2.25x-1 + 0.25x = -2.25x-1 + 2.25x-1 + -0.25x + 0.25x Combine like terms: -2.25x-1 + 2.25x-1 = 0.00 -0.75 + f2 + 2.25x-1 + 0.25x = 0.00 + -0.25x + 0.25x -0.75 + f2 + 2.25x-1 + 0.25x = -0.25x + 0.25x Combine like terms: -0.25x + 0.25x = 0.00 -0.75 + f2 + 2.25x-1 + 0.25x = 0.00 The solution to this equation could not be determined.
