Question

What should be the value of 'a' if the value of 2x^2 + x + a is equals to 6, when x=1.​

Answer 1

Answer:

Answer is 1

Step-by-step explanation:

2*1^2+1+a=6

4+1+a=6

5+a=6

a=6-5=1

Answer 2

Answer:

3

Step-by-step explanation:

2x^2 + x + a = 6

2(1×1) + (1) + a= 6 [Given : x = 1]

2(1) + 1 + a = 6

2 + 1 + a = 6

3 + a = 6

a = 6 - 3

a = 3
