Question

4. Simplify and find the value if m=-1.
(i) 2m -3 (m + 2)​

Answer 1

${\huge{\boxed{\bf{Answer}}}}$

• Put m = (-1) in the given equation.

$\colon\longrightarrow2m - 3(m + 2) \\ \\ \implies2( - 1) - 3( - 1 + 2) \\ \\ \implies - 2 - 3(1) \\ \\ \implies \: - 2 - 3 \\ \\ \implies \red{ - 5}$

Answer 2

Question:

simplify and find the value if m= -1

(i) 2m - 3 ( m + 2 )

Answer:

= 2m - 3 (m+2)

● Now substitute the value of m in given equation

= 2 ( -1 ) - 3 ( -1 + 2 )

= - 2 - 3 (1)

= - 2 - 3

= -5
