Question

Hasil Dari x2+x-72 : x-8

Answer 1

X² + x - 72
= x² + 9x - 8x - 72        -------> 9x - 8x = x
= x(x + 9) - 8(x + 9)
= (x - 8)(x + 9)
Maka :
{x² + x - 72 } : {x - 8}
= {(x - 8)(x + 9)} : {x - 8}
= x + 9

Answer 2

8 | 1 +1 -72
| 8 72
---------------- +
1 9 0
hasilnya = x + 9
dan sisanya = 0
