Question

fatore por agrupamento​

Answer 1

Explicação passo-a-passo:

a) 6x + 6y + ax + ay

6(x + y) + a (x + y)

(x + y)(6 + a)

b) ax + ay + 7x + 7y

a(x + y) + 7(x + y)

(x +y)(a + 7)

c) 2a + 2n + ax + nx

2(a + n) + x(a + n)

(a + n)(2 + x)

d) ax + 5bx + ay + 5by

x(a + 5b) + y(a + 5b)

(a + 5b)(x + y)

e) 3a - 3b + ax - bx

3(a - b) + x(a - b)

(a - b)(3 + x)

f) 7ax - 7a + bx - b

7a( x - 1 ) + b( x - 1 )

( x - 1 )( 7a + b)

g) 2x - 2 + yx - y

2(x - 1) + y(x - 1)

(x - 1)(2 + y)

h) ax + a + bx + b

a( x + 1 ) + b( x + 1 )

( x + 1 )( a + b )

i) $m^{2}$ + mx + mb + bx

m( m + x ) + b( m + x )

( m + x )( m + b )

j) $3a^{2}$ + 3 + $ba^{2}$ + b

3( $a^{2}$ + 1 ) + b( $a^{2}$ + 1 )

( $a^{2}$ + 1 )( 3 + b )

k) $x^{3}$ + $3x^{2}$ + 2x + 6

x( $x^{2}$ + 3x) + 2( x + 3)
