= 7
b. x-2-(-2x)+1+3x+4
= 6x + 3
c. x-2 + 2(-2x+1)
= x-2-4x+2
= -3x
d. (x-2)(3x+4)
= 3x^2 - 2x - 8
e. (x-2).7 (A+B-C tadi sudah dihitung hasilnya 7)
= 7x-14
f. (2(x-2) - 3(3x+4)).(-3(x-2)+2(-2x+4))
=(2x-4-9x-12).(-3x+6-4x+8)
=(-7x-16).(-7x+14)
= 49x^2-98+112-324
= 49x^2+14-324
kalau ada yang salah hitung maaf ya
