Simplifying F(x) = (x + 1)(x + -7) Multiply F * x xF = (x + 1)(x + -7) Reorder the terms: xF = (1 + x)(x + -7) Reorder the terms: xF = (1 + x)(-7 + x) Multiply (1 + x) * (-7 + x) xF = (1(-7 + x) + x(-7 + x)) xF = ((-7 * 1 + x * 1) + x(-7 + x)) xF = ((-7 + 1x) + x(-7 + x)) xF = (-7 + 1x + (-7 * x + x * x)) xF = (-7 + 1x + (-7x + x2)) Combine like terms: 1x + -7x = -6x xF = (-7 + -6x + x2) Solving xF = -7 + -6x + x2 Solving for variable 'x'. Reorder the terms: 7 + 6x + xF + -1x2 = -7 + -6x + x2 + 7 + 6x + -1x2 Reorder the terms: 7 + 6x + xF + -1x2 = -7 + 7 + -6x + 6x + x2 + -1x2 Combine like terms: -7 + 7 = 0 7 + 6x + xF + -1x2 = 0 + -6x + 6x + x2 + -1x2 7 + 6x + xF + -1x2 = -6x + 6x + x2 + -1x2 Combine like terms: -6x + 6x = 0 7 + 6x + xF + -1x2 = 0 + x2 + -1x2 7 + 6x + xF + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 7 + 6x + xF + -1x2 = 0 The solution to this equation could not be determined.
