Question

Descompuneti in factori!
1) 3x+3y
2) 6x+5xy
3) 4(x+2)+y(x+2)
4) 8x-8y+8a
5) 3x+3y+3z

6) 2x(x+1)-5(x+1)
Scoateti factor comun!
4(x+2)+3x(x+2)

Answer 1

1) 3x+3y=3(x+y)
2) 6x+5xy=x(6+5y)
3) 4(x+2)+y(x+2)=(x+2)(4+y)
4) 8x-8y+8a=8(x-y+a)
5) 3x+3y+3z=3(x+y+z)
6) 2x(x+1)-5(x+1)=(x+1)(2x-5)
7) 4(x+2)+3x(x+2)=(x+2)(4+3x)

Answer 2

Descompunem in factori:
1) 3x+3y=3(x+y)
2) 6x+5xy=x(6+5y)
3) 4(x+2)+y(x+2)=(x+2)(4+y)
4) 8x-8y+8a=8(x-y+a)
5) 3x+3y+3z=3(x+y+z)
6) 2x(x+1)-5(x+1)=(x+1)(2x-5)

Scoatem factorul comun:
4(x+2)+3x(x+2)=(x+2)(4+3x)

(x+2) e factorul comun
