(g) (3x²+4x2+3) . (4x³+4x²+5x)
(h) (4x²+3x+2) . (5x²+3x+3)

Answer 1

(3x² + 4x + 2)(2x² + 3x + 2) = (3x².2x² + 3x².3x + 3x².2) + (4x.2x² + 4x.3x + 4x.2) + (2.2x² + 2.3x + 2.2)

(3x² + 4x + 2)(2x² + 3x + 2) = 6x^5 + 3x³ + 6x² + 8x³ + 12x² + 8x + 4x² + 6x + 4

soma - se termos semelhantes

(3x² + 4x + 2)(2x² + 3x + 2) = 6x^5 + 11x³ + 22x² + 14x + 4
