Question

Factor completely and then place the factors in the proper location on the grid.25 a2 - 30 a + 9

Answer 1

the question is 25a^2-30a+9 right?

Answer 2

if that is the case, your factoring should look like this:
(5a-3)(5a-3)

because -3*-3 =9(right hand term) and
-3(5a)+-3(5a)
=-15a-15a
=-30a (middle term)

and 5a*5a=25a^2

Answer 3

not sure about the grid though. do they give you a grid?
