Question

Cual es el producto resultante de (x² + 2x + 4) (-x² - 3x -2)

Answer 1

Respuesta:

(x² + 2x + 4) (-x² - 3x -2) = x^4-5x^3-8x^2-12x-8

(x² + 2x + 4) (-x² - 3x -2)

= x²(-x²)+x²(-3x)+x²(2)+2x(-x²)+2x(-3x)+2x(-2)+4(-x²)+4(-3x)+4(-2)

= -x^4-3x^3+2x^2-2x^3-6x^2-4x-4x^2-12x-8

= -x^4+(-3-2)x^3+(2-6-4)x^2-12x-8

= -x^4+(-5)x^3+(-4-4)x^2-12x-8

= -x^4-5x^3+(-8)x^2-12x-8

= -x^4-5x^3-8x^2-12x-8
