tolong bantuin aku pake caranya yaa mksii bnyk

1. (a) 5a + 7a - 3a =(5a + 7a)- 3a= 12a - 3a = 9a
(b) 4u + 10y - 9u + 12uy= (4u - 9u)+ 10y + 12uy= -5u + 10y + 12uy
(c) 12a^2 + 8b + 16a^2= (12a^2 + 16^2)+ 8b= 28a^2 + 8b
(d) 6u^3+2y^2+y^2-5u^3= (6u^3 - 5u^3) + (2y^2 + y^2) = u^3+3y^2

2. (a) sama sprti 1(a)
(b)sama sprti 1(a)
(c) sama sprti 1(a)
(d) 9u + 6y + 10y + 8u = (9u+8u)+(6y+10y)= 17u+16y
(e) sama sprti 1(c)

1. a. (5a + 7a) - 3a = 12a - 3a = 9a
    b. 4x + 10y - 9x + 12xy = (4x - 9x) + 10y + 12xy = -5x + 10y +12xy
    c. 12a² + 8b + 16a² = (12a² + 16a²) + 8b = 28a² + 8b
    d. 6x³ + 2y² + y² - 5x³ = (6x³ - 5x³) + (2y² + y²) = x³ + 3y²

2. a. 7a - 10a = -3a
    b. -4x + 12x = 8x
    c. -15p + 9p = -6p
    d. 9x + 6y - 10y - 8x = (9x - 8x) + 6y - 10y = x - 4y
    e. 6q² - 8q + q² - 2q = (6q²+ q²) - 8q - 2q = 7q² - 10q
