Cevap:
1)3(x+2) =3x+6
2)3(x-8) = 3.x-3.8
=3x-24
3)5(x-1) =5x-5
4)x(x+4) = x.x+x.4
=x2+4x
5)(x-7).x =x.x-7.x
=x2-7x
6)(2x-5) (x+2) =2x(x+2)-5 (x+2)
=2x2 +4x-5x-10-x-10
=2x2-x-10
7)2x (x+1) =2x.x+2x.1
=2x2+2x
8)x.(x-7) =x.x-x.7
=x2-7x
9)3x. (x+4) =3x.x+3x.4
=3x2+12x
10)x (x+3) =x.x+x.3
=x2+3x
11)4.(x+3) =4x+12
12)8.(x+5) =4x+40
13)14.(x+4) =14x+56
14)(x-2) (x+1) =x.(x+1) -2 . (x+1)
=x2+x-2x-2
=x2-x-2
15)(x+2) (x+3) =x.(x+3)+2.(x+3)
=x2+3x+2x+6
=x2+5x+6
16)2. (x+8) =2x+16
17)5. (x+5) = 5x+25
18)2. (x+2 ) =2x+4
19)10. (x+3) =10x+30
20)11 .(x+5) =11x+55
