The standard equation of a polynomial as a function of "x" is expressed as:
[tex]f(x)=(x-a)(x-b)...(x-n)[/tex]where a, b and n are the zero's of the polynomial.
Given the following zeros -5 and 2, the required polynomial will be expressed as:
[tex]\begin{gathered} f(x)=(x-(-5))(x-2) \\ f(x)=(x+5)(x-2) \end{gathered}[/tex]Expand
[tex]\begin{gathered} f(x)=x(x)-2x+5x-5(2) \\ f(x)=x^2+3x-10 \end{gathered}[/tex]
