Question

Seder harnakanlah bentuk aljabar berikut :

( 1 ). 8p - 3 - 3p + 8
( 2). 2a - 1 + 2a - 2
( 3). 2a - b - a - b - 2
(4). 3x - 2 - 2 y + 3 - x + y
(5). 2m - n + 3m + 2n - 3
(6). 9m + 4mn + ( -12m ) - 7mn

Answer 1

Verified answer

1) 8p-3-3p+8= 8p-3p-3+8
= 5p+5
2) 2a-1+2a-2= 2a+2a-1-2= 4a-3
3) 2a-b-a-b-2= 2a-a-b-b-2= a-2b-2
4) 3x-2-2y+3-x+y= 3x-x-2+3-2y-y+3= 2x-x-1-y
5) 2m-n+3m+2n-3= 2m+3m+2n-3= 5m+n -3
6) 9m+4mn+(-12m)-7mn= 9m-12m+4mn-7mn= -3m-3mn

Answer 2

1.8p-3-3p+8
=80-30-3+8
=50p+5

2.2a-1+2a-2
=2a+2a-1-2
=4a-3

3.2a-b-a-b-2
=2a-a-b-b-2
=a-2b-2

4.3x-2-2y+3-x+y
=3x-x-2y+y-2+3
=2x-y+3

5.2m-n+3m+2n-3
=2m+3m-n+2n-3
=5m+n-3

6.9m+4mn+(-12m)-7mn
=9m+4mn-12m-7mn
=9m-12m+4mn-7mn
=-3m-3mn
=3(m-mn)
