Can someone help me expand this polynomial?

Step-by-step explanation:

=k^2 -(p+n)k+pn

this is the expanded form..

Multiply the first 2 terms in each brackets

k x k = k^2

Multiply the two outside terms in the brackets

k x - n = -kn

Multiply the two inside terms

-p x k = -pk

Multiply the last two terms

-p x -n = pn

Place all the values together to get your answer of:

k^2 - kn - pk + pn
