Answer 1

3a-3=3(a-1)

4+4x=4(1+x)

6m-6a=6(m-a)

8a-16=8(a-2)

15b+10=5(3b+2)

16b-12c=4 (4b-3c)

12x+36y=12(x+3y)

y-3y=y(1-3)=-2y

15a<do kwadratu>+12b<do kwadratu>=3(5a^2+4b^2)

24x<do kwadratu>-16y=8(3x-2y)

12a<do kwadratu>-8b=4(3a^2-2b)

10n-15m=5(2n-3m)

Answer 2

3a-3 = 3 ( a - 1)

4+4x = 4 ( 1 + x)

6m-6a = 6 ( m - a)

8a-16 = 8 ( a - 2)

15b+10 = 5 ( 3b + 2)

16b-12c = 4 (4b -3c)

12x+36y = 12 ( x + 3y)

y-3y = y ( 1- 3) = -2y

 

15a^2 + 12b = 3 (5a^2 + 4b)

 

24x^2 > - 16y

24x^2 + 16y > 0

8 ( 3x^2 + 2y) > 0

 

12a^2 > -8b

12a^2 + 8b > 0

4 ( 3a^2 +2b) >0

 

10n - 15m = 5 ( 2n - 3m)
