Question

A-2b+ab ; a=3, b=-1​

Answer 1

Solution :

★ a - 2b + ab .........(Given equation)

• Now, it is given that a = 3 and b = -1 by putting the values of a and b in given equation we get :]

➨ 3 - 2(-1) + (3)(-1)

➨ 3 + 2 - 3

➨ 2

Therefore, the required answer we get is 2.

Answer 2

Here,

a = 3

b = -1

Then,

$a - 2b + ab \\ = 3 - 2 \times ( - 1) + 3 \times ( - 1) \\ = 3 + 2 - 3 \\ = 5 - 3 \\ ⟶2$
