Sederhanakanlah! 1. 2 (a-b)+3 (2a-b) = 2. 3 (a+3)-2 (2a-1) = 3. -5 (2a-b+3) = 4. 2a+5-3 (2a-b-1) = 5. 2(3a-1)-2 (a-2b-1) = 6. (A+7)(a+5) = 7. (p-3)(p+3) = 8. (A

1.) 2a-2b + 6a-3b
2a+6a = -2b+(-3b)
8a = -5b

2.) 3a+9 - (-4a)+2
3a-(-4a) = 9+2
7a = 11

3.) -10a + 5b -15

4.) 4a²-2b-2a + 10a-5b-5 - 6a+3b+3
4a² + 10a-8a + 3b-7b -5+3
=4a² + 2a + (-4b) -2

5.) 6a-2 - (-2a)+4b+2
6a-2a+4b
4a+4b

6.) a²+5a + 7a+35
=a²+12a+35

7.) p²+3p -3p-9
=p²-9

8.) a²-ab -4a+4b

9.) 4p²-6p +6p-9
=4p²-9

10.) 9p-3p +(-3p)+1
=9p-(6p)+1
=3p+1
