a) x^ 2 – 12 x + m di habis dibagi x + 2
b) m x ^ 2 + x ^ 2 + x + 2 dibagi 3 X – 2 sisanya 4

a)
x + 2 = 0 → x = -2
x² – 12x + m di habis dibagi x + 2
(-2)² – 12(-2) + m = 0
4 + 24 + m = 0
m = -28 ✔
b)
3x – 2 = 0 → x = 2/3
mx² + x² + x + 2 dibagi 3x – 2 sisanya 4
m(2/3)² + (2/3)² + (2/3) + 2 = 4
4/9 m + 4/9 + 2/3 + 2 – 4 = 0
4/9 m – 8/9 = 0
m = 2 ✔
