Full solution

Q. \(4m^+

9

m)-(

6

+

2

m^)\

Write Problem and Distribute: Write down the problem and distribute the negative sign to the terms in the second parentheses. $\newline$ $(4m^2 + 9m) - (6 + 2m^2) = 4m^2 + 9m - 6 - 2m^2$
Combine Like Terms: Combine like terms by subtracting the coefficients of $m^2$ and the constant terms. $\newline$ $4m^2 - 2m^2 + 9m - 6 = 2m^2 + 9m - 6$
