Explain the connection between factors of a polynomial, zeros of a polynomial function, and solutions of a polynomial equation.

Factors of a polynomial, when set equal to zero and solved, become the zeros of a polynomial.  

The zeros of a polynomial are the numbers where the y-values are 0 which means the point will lie on the x-axis.  

Zeros and solutions are the same things. It is where the graph will cross the x-axis which means the y-value is zero.

I hope this is what you were looking for.

x+y=90

x=30-y=x
