GIVEN :-
- An Equation ; 2x² + x - a = 5
- x = 0.
TO FIND :-
- The value of a.
SOLUTION :-
➫ 2x² + x - a = 5
Now substitute the value of x = 0.
➫ 2 × (0)² + 0 - a = 5
➫ 2 × 0 + 0 - a = 5
➫ 0 + 0 - a = 5
➫ 0 - a = 5
➫ -a = 5 - 0
➫ -a = 5
➫ a = -5
Hence the value of a is (-5).
VERIFICATION :-
➫ 2x² + x - a = 5
Now substitute the value of x = 0 and a = (-5)
➫ 2 × (0)² + 0 - (-5) = 5
➫ 2 × 0 + 0 + 5 = 5
➫ 0 + 0 + 5 = 5
➫ 5 = 5
