1. Sederhanakan! A) 5x-6y-2z+7x+5y-11z B) 3x-9y-(4x-5y) 2.Tentukan perkalian dari A) -7y(4y) B) 5p(3q-3) C) (4y+1)(3y+2) 3.Tentukan pembagian dari A) 24x^3y^2÷(

1. a) 5x+7x-6y+5y-2z-11z = 12x+-y-13z
1. b) 3x-9y-(4x-5y) = 3x-9y-4x+5y= 3x-4x-9y+5y= -x-4y

2. a) -7y(4y) = -28y^2
2. b) 5p (3q-3) = 5pq -15p
2. c) (4y+1) (3y+2) = 12y^2 +8y +3y +2

3.a) 24x^3 3y^2 ÷ -4x^2 y =
3.

4.A) 5/(x+3)+3/(x-3) =
4.B) 8/4y-6/5xy =

5.A) (2p+3q)^2 = (2p+3q) (2p+3q) = 4p^2+6pq+6pq+9q^2 = 4p^2+12pq+9q^2
5.B) (a-4)^2 = (a-4)(a-4) = a^2-4a-4a+16= a^2-8a+16
5.C) 3/x+3/y÷3/x-3/y =

maap kalo ada yg belum

1.A , 5x +7x -6y +5y -2z -11z= 12x -y - 13z
B, 3x -9y -(4x -5y) = 3x - 9y -4x +5y = 3x -4x -9y +5y = -x - 4y

2A. -7y (4y) = -28y^2
B. 5p (3q-3)= 15pq - 15p
C. (4y +1)(3y +2)= 4y (3y +2) +1 (3y +2) = 12y^2 +8y + 3y +2 = 12y^2 +11y +2

3A. 24x^3y^2 : ( -4x^2y) = (24/-4)×(x^3/x^2)×(y^2/y) = -6 x y

5A. (2p +3q)(2p+3q) = 2p (2p+3)+3q (2p +3)= 4p^2 +6p + 6pq +9q
B, (a-4)(a-4)= a ( a-4) -4 (a-4) = a^2 -4a -4a +16 = a^2 -8a +16
