1.

2.

3.Option 4
Explanation:
1.We are given that a polynomial

We have to write the given polynomial in standard form
In order to write the polynomial in standard form then we arrange the terms in polynomial according to increasing power of x

It is required standard form of given polynomial .
2.We are given that a polynomial

We have to simplify the polynomial


3.We are given that an expession
![(2x-3)+[4x(3x+2)]](https://img.qammunity.org/2019/formulas/mathematics/high-school/s3df49hkjccefel81mj5pxpxw6twup6ro1.png)
We have to find the value of a polynomial which is equivalent to given expression


Hence ,option 4 is true.
