Answer:
2x - 3
x - 9
Step-by-step explanation:
The root of a problem is the x value that makes the equation equal to zero.
If the factored form of the equation is (2x-3)(x-9) that means if either 2x - 3 or x - 9 is equal to zero, the entire equation will equal zero, because zero times any number is equal to zero.
Therefore you must solve for (2x-3)=0 and (x-9)=0
