Simplifying f(x) = 5x2 + 7x + -5(f + g)(x) Multiply f * x fx = 5x2 + 7x + -5(f + g)(x) Reorder the terms for easier multiplication: fx = 5x2 + 7x + -5x(f + g) fx = 5x2 + 7x + (f * -5x + g * -5x) fx = 5x2 + 7x + (-5fx + -5gx) Reorder the terms: fx = -5fx + -5gx + 7x + 5x2 Solving fx = -5fx + -5gx + 7x + 5x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '5fx' to each side of the equation. fx + 5fx = -5fx + -5gx + 7x + 5fx + 5x2 Combine like terms: fx + 5fx = 6fx 6fx = -5fx + -5gx + 7x + 5fx + 5x2 Reorder the terms: 6fx = -5fx + 5fx + -5gx + 7x + 5x2 Combine like terms: -5fx + 5fx = 0 6fx = 0 + -5gx + 7x + 5x2 6fx = -5gx + 7x + 5x2 Divide each side by '6x'. f = -0.8333333333g + 1.166666667 + 0.8333333333x Simplifying f = -0.8333333333g + 1.166666667 + 0.8333333333x Reorder the terms: f = 1.166666667 + -0.8333333333g + 0.8333333333x
