Simplifying (x + -8)(x + 7) = -2r Reorder the terms: (-8 + x)(x + 7) = -2r Reorder the terms: (-8 + x)(7 + x) = -2r Multiply (-8 + x) * (7 + x) (-8(7 + x) + x(7 + x)) = -2r ((7 * -8 + x * -8) + x(7 + x)) = -2r ((-56 + -8x) + x(7 + x)) = -2r (-56 + -8x + (7 * x + x * x)) = -2r (-56 + -8x + (7x + x2)) = -2r Combine like terms: -8x + 7x = -1x (-56 + -1x + x2) = -2r Solving -56 + -1x + x2 = -2r Solving for variable 'x'. Reorder the terms: -56 + 2r + -1x + x2 = -2r + 2r Combine like terms: -2r + 2r = 0 -56 + 2r + -1x + x2 = 0 The solution to this equation could not be determined.
