how to simplify 6(49x*21)/6x(42x+18)
thanks
edit: and also 10x^2+42x+36 simplify
Simplify the following:
(6×49×21 x x (42 x+18))/6
(49 x×21×6 x (42 x+18))/6=6/6×49 x×21 x (42 x+18)=49 x×21 x (42 x+18):
49×21 x x (42 x+18)
Factor 6 out of 42 x+18:
49×21 x x×6 (7 x+3)
49 x×21 x×6 (7 x+3)=49 x^2×21×6 (7 x+3):
49×21×6 x^2 (7 x+3)
49×21 = 1029:
1029×6 x^2 (7 x+3)
1029×6 = 6174:
Answer: | 6174x^2 (7x + 3 )
