Sederhanakan bentuk aljabar berikut. a. 5x - 3x b. 9 + 4x - 1 c. 4x - 8x+ 12 d. 7 - 2x -x +5 e. ... Tolong Jawab Ya Kak... Pakai Cara Tnks :D (Info Lebih Lanjut

a. 5x - 3x
= (5 - 3)x
= 2x

b. 9 + 4x -1
= 4x + 9 - 1
= 4x + 8
= 4(x + 2)

c. 4x - 8x + 12
= (4 - 8)x + 12
= -4x + 12
= 4(3 - x)

d. 7 - 2x - x + 5
= -2x - x + 7 + 5
= (-2 - 1)x + 12
= -3x + 12

e. 3x² + 3y² - 5xy + 2x² - 5y² + 6xy
= 3x² + 2x² + 3y² - 5y² + 6xy
= (3 + 2)x² + (3 - 5)y² + 6xy
= 5x² - 2y² + 6xy

a] 5x - 3x = 2x
b] 9 + 4x - 1 = 4x + 8
c] 4x - 8x + 12 = -4x + 12
d] 7 - 2x - x + 5 = -3x + 12
e] 3x^2 + 3y^2 - 5xy + 2x^2 - 5y^2 + 6xy
= 5x^2 - 2y^2 + xy
