Simplifying F(x) = -1(x + -1)(x + -7) Multiply F * x xF = -1(x + -1)(x + -7) Reorder the terms: xF = -1(-1 + x)(x + -7) Reorder the terms: xF = -1(-1 + x)(-7 + x) Multiply (-1 + x) * (-7 + x) xF = -1(-1(-7 + x) + x(-7 + x)) xF = -1((-7 * -1 + x * -1) + x(-7 + x)) xF = -1((7 + -1x) + x(-7 + x)) xF = -1(7 + -1x + (-7 * x + x * x)) xF = -1(7 + -1x + (-7x + x2)) Combine like terms: -1x + -7x = -8x xF = -1(7 + -8x + x2) xF = (7 * -1 + -8x * -1 + x2 * -1) xF = (-7 + 8x + -1x2) Solving xF = -7 + 8x + -1x2 Solving for variable 'x'. Reorder the terms: 7 + -8x + xF + x2 = -7 + 8x + -1x2 + 7 + -8x + x2 Reorder the terms: 7 + -8x + xF + x2 = -7 + 7 + 8x + -8x + -1x2 + x2 Combine like terms: -7 + 7 = 0 7 + -8x + xF + x2 = 0 + 8x + -8x + -1x2 + x2 7 + -8x + xF + x2 = 8x + -8x + -1x2 + x2 Combine like terms: 8x + -8x = 0 7 + -8x + xF + x2 = 0 + -1x2 + x2 7 + -8x + xF + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 7 + -8x + xF + x2 = 0 The solution to this equation could not be determined.
