nih tambahlagi poin nya banyak oh ya + cara ya
Penjelasan dengan langkah-langkah:
A. ( 5z + 3) - ( 2z - 7) =
5z + 3 - ( 2z + 7)
5z + 3 - 2z + 7
3z + 3 + 7 =
3z + 10
B. ( 5m - 1) - ( m + 4) =
5m - 1 - ( m + 4)
5m - 1 - m - 4
4m - 1 - 4 =
4m - 5
C.
[tex](3x {}^{2} + 4x - 2) - (2x { }^{2} - 6x + 8) = [/tex]
[tex]3x {}^{2} + 4x - 2 - (2x { }^{2} - 6x + 8)[/tex]
[tex]3x + 4x - 2 - 2x {}^{2} + 6x - 8[/tex]
[tex]x {}^{2} + 4x - 2 + 6x - 8[/tex]
[tex]x { }^{2} + 10x - 2 - 8 = [/tex]
[tex]x {}^{2} + 10x - 10[/tex]
D.
[tex](4a - 5b + 4c) - (a - 6b + 2c) = [/tex]
[tex]4a - 5b + 4c - (a - 6b + 2c)[/tex]
[tex]4a - 5b + 4c - a + 6b - 2c[/tex]
[tex]3a - 5b + 4c + 6b - 2c[/tex]
[tex]3a + b + 4c - 2c = [/tex]
[tex]3a + b + 2c[/tex]
