Question

The value of 2(a² + ab + 3) - ab when a = 5 and b = -3, is

A.

23

B.

35

C.

41

D.

53

Correct option is C

The given expression is:
2(a² + ab + 3) - ab
We are also given that:
a = 5 and b = -3
Substituting a = 5 and b = -3 in the expression, we get:
= 2(5² + 5(-3) + 3) - 5(-3)
Simplifying the expression, we get:
= 2(25 - 15 + 3) + 15
= 2(13) + 15
= 26 + 15 = 41
