Sederhanakan bentuk aljabar berikut: a. 5x-3x b.9+4x-1 c.4x-8x+12 d.7-2x-x+5 e.3x²+3y²-5xy+2x²-5y²+6xy

a.
5x - 3x = 2x

b.
9 + 4x - 1
= 8 + 4x

c.
4x - 8x + 12
= -4x + 12

d.
7 - 2x - x + 5
= -3x + 12

e.
3x" + 3y" - 5xy + 2x" - 5y" + 6xy
= 5x" - 2y" + xy

Ket :
" = kuadrat

Semoga membantu dan semoga bermanfaat...

Siap boss

a. 5x - 3x
= (5-3)x
= 2x
b. 9 + 4x - 1
= 4x + (9 - 1)
= 4x + 8
c. 4x - 8x + 12
= (4 - 8)x + 12
= -4x + 12
= 4(3 - x)
d. 7 - 2x - x + 5
= 7+5 + (-2 -1)x
= 12 -3x
e. 3x² + 3y² - 5xy + 2x² - 5y² + 6xy
= (3+2)x² + (3 - 5)y² + (6 - 5)xy
= 5x² - 2y² + xy
