9. What should be the value of a if the value of 2x2 + x - a equals to 5, when x=0?​

Answer 1

Friends…!

What should be the value of a, if the value of 2x2+x-a equals to 5 and x=0?

2 × 2 + x - a = 5

Substituting the value of x in the equation

2 × 2 + 0 - a = 5

4 + 0 - a = 5

4 - a = 5

4 - 5 = a

—1 = a

Thus a = —1

Answer : The value of a is —1
