Question

Fatore os polinômios :

a) ab + ac + 10b + 10c

b) xy^2 + xy^3 + 3 + 3y

c) 4x + 12 + xy +3

Answer 1

Resposta:

A)

$ab + ac + 10b + 10c \\ a.(b + c) + 10(b + c) \\ (b + c).(a + 10)$

B)

${xy}^{2} + {xy}^{3} + 3 + 3y \\ {xy}^{2} .(1 + y) + 3(1 + y) \\ (1 + y).( {xy}^{2} + 3)$

C)

$4x + 12 + xy + 3 \\ 4x + 15 + xy$
