Question

Considerando os polinômios A =2x+3,B=4x-2e(=x+5),efetue​

Answer 1

Resposta:

a) B^2

$(4x - 2) {}^{2} \\ 8 {x}^{2} - 16x + 4$

b) (A + B) . (A + C)

$(2x + 3 + 4x - 2) \times (2x + 3 + x + 5) \\ (6x + 1) \times (3x + 8) \\ 18 {x}^{2} + 48x + 3x + 8 \\ 16 {x}^{2} + 51x + 8$

C) (B - C) . (C + B)

$(4x - 2 - x + 5) \times (x + 5 + 4x - 2) \\ (3x + 3) \times (5x + 3) \\ {15x}^{2} + 9x + 15x + 9 \\ {15x}^{2} + 24x + 9$
