Respuesta :
=(x-4)(2x-5x+3)
=(x-4)(-3x+3)
=-3x²+3x-12x-12
=-3x²-9x-12
=-6x-12
=x=-12/6
=x=-2
=(x-4)(-3x+3)

=-6x-12
=x=-12/6
=x=-2
The answer is x³ - 9x² + 23x - 12
Let's use distributive property method:
(x - 4)(x² - 5x + 3) = x * x² + x * (-5x) + x * 3 - 4 * x² - 4 * (-5x) - 4 * 3 =
= x³ - 5x² + 3x - 4x² + 20x - 12 =
= x³ - 9x² + 23x - 12
Let's use distributive property method:
(x - 4)(x² - 5x + 3) = x * x² + x * (-5x) + x * 3 - 4 * x² - 4 * (-5x) - 4 * 3 =
= x³ - 5x² + 3x - 4x² + 20x - 12 =
= x³ - 9x² + 23x - 12
