You can use long division or synthetic division. (I used synthetic division below)
8║2 -15 -10 +16
║ 16 8 -16
2 1 -2 0 → 2x² + x - 2
We are given that
We have to find the value of quotient
Dividened: It is defined as the value which are divided by dividened.
Divisor: It is defined as the value by which we are divide the dividened.
Quotient: It is defined as the value obtained when we are dividing the dividened by divisor .
After dividing then we get
2x² + x - 2
