Answer:
[tex]x^{2} - 9x +18[/tex]
Step-by-step explanation:
To solve the question work backwords. First, set an equation equal to 0 where the solutions are 6 and 3. For example, (x-6)(x-3)=0. Then, use FOIL to multiply it out. When it is multiplied you are left with the function [tex]x^{2} - 9x +18[/tex].
