Question

Fatore, por agrupamento, os polinômios

Answer 1

a)

5x - xy + 15 - 3y
x(5 - y) + 3(5 - y)
(5 - y)(x + 3)

b)

2ax+ 3a + 4bx + 6b
a(2x + 3) + 2b(2x + 3)
(2x + 3)(a + 2)

c)

xy + 2x + 4y + 8
x(y + 2) + 4(y + 2)
(y + 2)(x + 4)

d)
x³ + 3x² + 2x + 6
x²(x + 3) + 2(x + 3)
(x + 3)(x² + 2)

e)

2ax + x + 6a + 3
x(2a + 1) + 3(2a + 1)
(2a + 1) (x + 3)
