Question

factoring: 4m^4-37m^2+9

Answer 1

\[ (m-3) (3+m) (2 m-1) (1+2 m) \]

Answer 2

@FoolForMath why dont you use m+3 and 2m+1 to make the result look prettier ;)

Answer 3

(2m^2+3)^2-(7m)^2
=(2m^2-7m+3)(2m^2+7m+3)
=(2m-1)(m-3)(2m+1)(m+3)

Answer 4

Yifan12879: Indeed, but I type faster in that way.

Answer 5

why is it that 7m was in both sides? that -7m and +7m?

Answer 6

thanks :)
