Step-by-step explanation:
- Properties of Exponent -
![(a^m)/(a^n)=a^(m-n)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/hzlepg3qz3yeov7wjk4bdlzjfmkevroqdr.png)
Our a is y+1
Our m is 5
Our n is 3
![((y+1)^5)/((y+1)^3)=(y+1)^(5-3)\\(y+1)^2](https://img.qammunity.org/2021/formulas/mathematics/high-school/ur0gjb3yjnd2r06dymevlh0qnsrb3b1voz.png)
- Multiply The Polynomial -
As for the Quadratic Polynomial and being squared, we use the following formula:
![(x+y)^2=x^2+2xy+y^2](https://img.qammunity.org/2021/formulas/mathematics/high-school/b3mao47laazrdj08lrt3w6arwhs7gu5h43.png)
Our x is y
Our y is 1
Thus,
![(y+1)^2=y^2+2(y)(1)+1^2\\(y+1)^2=y^2+2y+1](https://img.qammunity.org/2021/formulas/mathematics/high-school/4w4skznze4x0sce8a8i3glxbrkal1zsoto.png)
As our simplified, multiplied form is
![y^2+2y+1](https://img.qammunity.org/2021/formulas/mathematics/high-school/npmajm8y5jg39r8w5uzqhsqmdx5o5tnbbw.png)
