Question

Sejam os polinômios f(X) = 2X+3, g(X) =-4X+3 e h(X) = 3X²-5X+4 Determine o polinômio P(X) = f(X).g(X)+h(X)

*****caso precise (¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹)*****

Answer 1

p(x)= f(x) . g(x) + h. (x)

p(x) = (2x + 3).(- 4x + 3) + 3x² - 5x +4

p(x) = - 8x + 6x -12x + 9 + 3x² - 5x + 4

p(x) = 3x² - 8x +6x - 12x - 5x +9 +4

p(x) = 3x² -19x + 13

Answer 2

P(x) = (2x+3)(-4x+3) + h(x)
P(x) = -8x² + 6x -12x + 9 + 3x² -5x + 4
P(x) = -5x² -11x +13
