The complete question is, Simplify the expression and find its value when a=5 and b=-3
2 (a² + ab) + 3 - ab
Given:
The expression 2 (a² + ab) + 3 - ab
To find:
Simplify the expression and find its value when a=5 and b=-3
Solution:
From the given information, we have the data as follows.
The expression 2 (a² + ab) + 3 - ab
Firstly we will solve the expression.
2 (a² + ab) + 3 - ab
= 2a² + 2ab + 3 - ab
= 2a² + ab + 3
Now, we will substitute the values of a and b, that is, a = 5 and b = -3 in the above equation.
= 2 (5)² + 5 × (-3) + 3
= 2 (25) - 15 + 3
= 50 - 15 + 3
= 38
Therefore, the value of the expression 2 (a² + ab) + 3 - ab is 38.
