Question

find factors of the quadratic equation by factorisation method
$7 {m}^{2} = 21m$

Answer 1

Hey

Here is your answer,

7m^2 =21m
7m^2 -21m=0
7m(m-3)=0
7m=0
M=0
m-3=0
m=3

Hope it helps you!

Answer 2

Hey There!

Here, you can factorise and solve it as follows:

$7m^2 = 21m \\ \\ \implies m^2 = \frac{21}{7}m \\ \\ \implies m^2 = 3m \\ \\ \implies m^2-3m=0 \\ \\ \implies m(m-3)=0 \\ \\ \implies m=0 \, \,OR \, \, m-3=0 \\ \\ \implies \boxed{m=0} \, \, \, OR \, \, \, \boxed{m=3}$
