![Constant \to 8](https://img.qammunity.org/2022/formulas/mathematics/high-school/5l96cocegblx9y6yij8nvx07cfz05dzdbe.png)
![Type \to Binomial](https://img.qammunity.org/2022/formulas/mathematics/high-school/am4ifxsfmt1w43invcu89z0e32bwk3iht1.png)
Required
Which of the options is true
![Type \to Binomial](https://img.qammunity.org/2022/formulas/mathematics/high-school/am4ifxsfmt1w43invcu89z0e32bwk3iht1.png)
This implies that the polynomial has just 2 terms
The above shows that (a), (b) and (c) are not true because they have more than 2 terms
![Degree \to 3rd](https://img.qammunity.org/2022/formulas/mathematics/high-school/t9109fir97c50sxqy4nfwosah0ngkqyd2v.png)
This implies that the highest power of x is 3

The second term of the polynomial must be +8
Only (d) satisfy the above conditions
