Question

Multiplique os polinômios:



(x + 2) . (x + 3)

(a - 2) . (a – 7)

(y + 6) . (y - 6)

(2x - 5) . (3x - 2)

(1 – 2x) . (4 + 3x)

(-x + 4) . (x + 5)

Answer 1

(x + 2) . (x + 3)

x.x+3x+2x+2×3

x²+5x+6

(a - 2) . (a – 7)

a.a-7a-2a-2×7

a²-9a-14

(y + 6) . (y - 6)

y²-6²

y²-36

(2x - 5) . (3x - 2)

2x.3x-2x.2-5.3x-5.-2

6x²-19x+10

(1 – 2x) . (4 + 3x)

4+3x-2x.4-2x.3x

4+3x-8x-6x²

-6x²-5x+4

(-x + 4) . (x + 5)

-x.x-5x+4x+4×5

-x²-x+20
