Answer:
The equation
has roots –2 and 1/5.
Hence, the option 'a' is the correct answer.
Step-by-step explanation:
Checking the equation

putting x = -2 in the equation





L.H.S=R.H.S
putting x = 1/5 in the equation





L.H.S=R.H.S
As putting x = -2 and x = 1/5 satisfy the equation.
Therefore, the equation
has roots –2 and 1/5.
Hence, the option 'a' is the correct answer.
Number 2 is already a mixed number. But it says mixed number as a decimal. So -1 29/40 as a decimal is -1.725.
