Question

(1) 21m² + 7m wtah is the answer of this question​

Answer 1

7÷21m^2

=7×3m

=21m^2

=3m is a write answer

Answer 2

Given:

We have an equation is given which is 21m² + 7m.

To Find:

We have to simplify the equation?

Step-by-step explanation:

• An equation is given to us which is 21m² + 7m'
• We can simplify the given equation by taking the common terms out from the given equation

• As we can see that both the term os equation has 7m is in the common thus we can take it out as common factor and write it as

       $21m^2+7m=7m(3m+1)$

• If we want to further simplify the equation to find the roots of equation or to find the value of m we can do it by the equating the above equation with 0.

       $7m(3m+1)=0$

• Now equatew both the terms with 0 we get

      $7m=0,3m+1=0\\m=0.m=\frac{-1}{3}$

Hence the values of m are $0.\frac{-1}{3}$
