Question

12
Solve the following quadratic equations by factorization.
7m' = 21m​

Answer 1

Answer:

Step-by-step explanation:

7m'=21m

7m'-21m=0

7m(m-3) =0

7m=0 or m-3=0

m=0 or m=3

Answer 2

Answer:

Step-by-step explanation:

7 $m^{2}$ - 21 m =0

7 m(m - 3 ) =0

7 m = 0

m - 3 = 0

So;

m=0

OR

m=3
