a)(3x-2)(2x+3)-(6x² -12)=6x²+9x-4x-6-6x²+12=5x+6
b) 6a² +5a (-a+2)-(4a-3)=6a²-5a²+10a-4a+3=a²+6a+3

a) 4ab-7cb=b(4a-7c)
b) 15x+27y=3(5x+9y)
c) 4x³y-10x²y²+2xy²=2xy(2x²-5xy+y)
1.
A
(3x-2)(2x+3)-(6x2-12)=
6x2 + 9x-4x-6-6x2+12=
5x+6
B
6a2+5a(-a+2)-(4a-3)=
6a2-5a2+10a-4a+3=
-a2+ 6a+3
2.
4ab -7cb=
b(4a-7c)
15x+27y=
3(5x+8y)
C
4 x2y-10 x2y2+ 2 xy2=
2y(2x2-5 x2y+ xy)
proszę Bardzo,licze na naj!!!!!!!!!!!!!!!!!!!!!
