Simplify the Expression and Find its Value when $a=5$ and $b=-3$.
$2(a^2+ab)+3-ab$
Given: Expression: $2(a^2+ab)+3-ab$
To do: To simplify the Expression and Find its Value when $a=5$ and $b=-3$.
Solution:
From the question it is given that $a=5$ and $b=-3$
We have,
$=2a^2+2ab+3-ab$
$=2a^2+ab+3$
Then, Substitute the value of $a$ and $b$ in the Equation
$=(2\times 5^2)+(5\times (-3))+3$
$=(2\times 25)+(-15)+3$
$=50 - 15+3$
$=53-15$
$=38$
