Rodney Mason · Answer 1

7x^2 put them both on one side then u have 7x^2 - 175 = 0 then u factor it and u get 7 (x^2 - 25) = 0

Maddison · Answer 2

7x^2=175

subtract 175 from both sides

7x^2-175=0

then factor out 7

7 (x^2-25)

so now it would be easy to figure out that

(x^2-25) = (x+5) (x-5)

so now the answer is

7 (x-5) (x+5)
