Question

4m^2+3m^2+(-6m^2)+m^2​

Answer 1

CONCEPT :

There are constants and variables in a algebraic expression.

Variables - The alphabets in the equation are called variables. ( Ex - a, c , e , x)

Constants - A number having a numerical value. ( Ex - 1,6,9 )

Answer :

2m²

Question:

$\mathtt{{4m}^{2}+{3m}^{2}+({-6m}^{2})+{m}^{2}}$

Step by step explanation :-

$\mathtt{= {4m}^{2}+{3m}^{2}-{6m}^{2}+{m}^{2}}$

$\mathtt{= {8m}^{2}-{6m}^{2}}$

$\boxed{\sf{= {2m}^{2}} }$

Hence, The solution of the equation is 2m².

More explanation :

You can use these important steps while solving any equations like this :-

( + ) × ( − ) = ( − ) - This was used in your question.

( + ) × ( + ) = ( + )

( - ) × ( + ) = ( - )

( - ) × ( - ) = ( + )
