Simplifying (4x + 9)(x + -3) = y Reorder the terms: (9 + 4x)(x + -3) = y Reorder the terms: (9 + 4x)(-3 + x) = y Multiply (9 + 4x) * (-3 + x) (9(-3 + x) + 4x * (-3 + x)) = y ((-3 * 9 + x * 9) + 4x * (-3 + x)) = y ((-27 + 9x) + 4x * (-3 + x)) = y (-27 + 9x + (-3 * 4x + x * 4x)) = y (-27 + 9x + (-12x + 4x2)) = y Combine like terms: 9x + -12x = -3x (-27 + -3x + 4x2) = y Solving -27 + -3x + 4x2 = y Solving for variable 'x'. Combine like terms: y + -1y = 0 -27 + -3x + 4x2 + -1y = 0 The solution to this equation could not be determined.
