Tentukan hasil bagi a. 4x2 +16x +15 oleh (2x + 5) b. 4x3 +12x2 − x −15 oleh x −1 c. 4x3 +12x2 − x −15 oleh 2x2 + 3x − 5

a]

2x + 5 / 4x^2 + 16x + 15 \ 2x + 3
...............4x^2 + 10x
............---------------------------- -
..............................6x + 15
..............................6x + 15
...........----------------------------- -
...................................0

b]

x - 1 /4x^3+12x^2-x-15\ 4x^2+16x+15
...........4x^3 - 4x^2
......-------------------------- -
.................16x^2-x-15
.................16x^2-16x
......-------------------------- -
...........................15x-15
...........................15x-15
......-------------------------- -
.............................0

c]

2x^2+3x-5 / 4x^3+12x^2-x-15 \ 2x+3
.......................4x^3+6x^2-10x
..................------------------------------- -
..................................6x^2+9x-15
..................................6x^2+9x-15
