Question

Check whether x = -1 is a solution of equation 4x2 – 3x – 1 = 0

​

Answer 1

No x ≠ -1 is a solution of equation 4x2 – 3x – 1 = 0

Answer 2

Answer:

no

Step-by-step explanation:

put x=-1 and if eqn satisfies then it is root if not then it is not root

Let see

4(-1)^2-3(-1)-1=0

4+3-1=0

but

6 is not equal to 0

therefore -1 is not root of the given equation
