Sederhanakan bentuk aljabar berikut 1.4x+2x+2x= 2.8x-3x+2x-2x= 3.2x(8+2x)+3(6-7x)= 4.4(ab-3ac-7c)+2ab-2c(a+4)= 5.2p-2q+3p+4q=

1.4x+2x+2x
= 8x
2.(8x-3x)+(2x-2x)
= 5x
3.2x(8+2x)+3(6-7x)
= 16x+4x²+18-21x
= 4x²-5x+18
4.4(ac+8cab-3ac-7c)+2ab-2c(a+4)
= 4ab-12ac-28c+2ab-2ca+8c
= 8ab-14ac-20c
5.2p-2q+3p+4q
=5p+2q
