Given: Expression: $2x^2+x-a$

To do: To find the value of $a$ if the value of $2x^2+x-a$ equals to $5$, when $x=0$.

Solution: From the question, it is given that $x=0$


We have,


$2\times 2+x-a=5$


$a=2\times 2+x-5$


Then, Substitute the value of $x$ in the Equation


$a=(2\times 02)+0-5$


$a=0+0-5$


$a=-5$
