Create a quadratic equation that can be solved by factoring. give the factored answer.

Quadratic eq standard form is

Ax^2+bx+c=0

a, b and c are known values. 
a can't be 0."x" is the variable 

lets take an example

x^2 − 4x+2 = 0

x^2-2x-2x+2=0
x(x-2) - 1(x-2)=0

x=1,2

Are you asking for 6 or 15?
