Simplifying f(x) = x2 + 7x + 8whatisf(-1x) Multiply f * x fx = x2 + 7x + 8whatisf(-1x) Remove parenthesis around (-1x) fx = x2 + 7x + 8afhistw * -1x Reorder the terms for easier multiplication: fx = x2 + 7x + 8 * -1afhistw * x Multiply 8 * -1 fx = x2 + 7x + -8afhistw * x Multiply afhistw * x fx = x2 + 7x + -8afhistwx Reorder the terms: fx = -8afhistwx + 7x + x2 Solving fx = -8afhistwx + 7x + x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '8afhistwx' to each side of the equation. 8afhistwx + fx = -8afhistwx + 7x + 8afhistwx + x2 Reorder the terms: 8afhistwx + fx = -8afhistwx + 8afhistwx + 7x + x2 Combine like terms: -8afhistwx + 8afhistwx = 0 8afhistwx + fx = 0 + 7x + x2 8afhistwx + fx = 7x + x2 Reorder the terms: 8afhistwx + fx + -7x + -1x2 = 7x + -7x + x2 + -1x2 Combine like terms: 7x + -7x = 0 8afhistwx + fx + -7x + -1x2 = 0 + x2 + -1x2 8afhistwx + fx + -7x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 8afhistwx + fx + -7x + -1x2 = 0 Factor out the Greatest Common Factor (GCF), 'x'. x(8afhistw + f + -7 + -1x) = 0Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing f to the left, all other terms to the right. Add '-1x' to each side of the equation. x + -1x = 0 + -1x Remove the zero: 0 = -1x Simplifying 0 = -1x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(8afhistw + f + -7 + -1x)' equal to zero and attempt to solve: Simplifying 8afhistw + f + -7 + -1x = 0 Reorder the terms: -7 + 8afhistw + f + -1x = 0 Solving -7 + 8afhistw + f + -1x = 0 Move all terms containing f to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 8afhistw + f + 7 + -1x = 0 + 7 Reorder the terms: -7 + 7 + 8afhistw + f + -1x = 0 + 7 Combine like terms: -7 + 7 = 0 0 + 8afhistw + f + -1x = 0 + 7 8afhistw + f + -1x = 0 + 7 Combine like terms: 0 + 7 = 7 8afhistw + f + -1x = 7 Add 'x' to each side of the equation. 8afhistw + f + -1x + x = 7 + x Combine like terms: -1x + x = 0 8afhistw + f + 0 = 7 + x 8afhistw + f = 7 + x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
