Simplifying -2(x + -7)(x + 2) = y Reorder the terms: -2(-7 + x)(x + 2) = y Reorder the terms: -2(-7 + x)(2 + x) = y Multiply (-7 + x) * (2 + x) -2(-7(2 + x) + x(2 + x)) = y -2((2 * -7 + x * -7) + x(2 + x)) = y -2((-14 + -7x) + x(2 + x)) = y -2(-14 + -7x + (2 * x + x * x)) = y -2(-14 + -7x + (2x + x2)) = y Combine like terms: -7x + 2x = -5x -2(-14 + -5x + x2) = y (-14 * -2 + -5x * -2 + x2 * -2) = y (28 + 10x + -2x2) = y Solving 28 + 10x + -2x2 = y Solving for variable 'x'. Combine like terms: y + -1y = 0 28 + 10x + -2x2 + -1y = 0 The solution to this equation could not be determined.
