3 m ( 2 m + 9 ) = 0 3 m = 0 ∨ 2 m + 9 = 0 m = 0 ∨ 2 m = − 9/ : 2 m = 0 ∨ m = − 2 9 m = 0 ∨ m = − 4 2 1
The equation 3 m ( 2 m + 9 ) = 0 has two solutions: m = 0 and m = − 2 9 (or m = − 4.5 ). This can be found by setting each factor of the equation to zero. To solve, we considered the factors 3 m and 2 m + 9 .
