25x^2 - 60x + 36

highest number they all go into is 1

so would this be Prime?

• Factor Completely -

25 = 5 * 5 or 25*1
36 is 1*36, 2*18, 3*12 , 4*9 , 6*6
hmm, 6 times 5 is 30 and two 30s is 60
so try
(5 x - 6)(5x-6)

• Factor Completely -

ok when I foil that I get the equation

so I would I show my work?

• Factor Completely -

The only thing I can suggest is show all the factors of 25 and 36 as I did.

• Factor Completely -

thanks
