Question

factor completley 2r-6-6r+18

Answer 1

Answer choices???

Answer 2

solve by grouping...based upon your other questions.

so let's rewrite to regroup variables that are related.

Answer 3

2r-6-6r+18 = 0
2r -6r -6 +18 = 0
-4r +12 = 0
-4r = -12
r = 4

actually you could just combine like terms. Don't forget the =0 that is very important because with out you are not able to "solve"

Answer 4

Or if you wrote the problem wrong...with "factoring" I think you did..check that please

Answer 5

2r-6-6r+18 = 2r-6r-6+18 = 2r(1-3)-6(1-3) = (2r-6)(1-3)

Answer 6

agreed!

Answer 7

you can re-check the factor (2r-6)(1-3)... you'll get the same
