14 + 2x = (14 + 2x)(-5 + x)

Multiply (14 + 2x) * (-5 + x)
14 + 2x = (14(-5 + x) + 2x * (-5 + x))
14 + 2x = ((-5 * 14 + x * 14) + 2x * (-5 + x))
14 + 2x = ((-70 + 14x) + 2x * (-5 + x))
14 + 2x = (-70 + 14x + (-5 * 2x + x * 2x))
14 + 2x = (-70 + 14x + (-10x + 2x2))

Combine like terms: 14x + -10x = 4x
14 + 2x = (-70 + 4x + 2x2)

Solving
14 + 2x = -70 + 4x + 2x2

Solving for variable 'x'.
