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.
Given the polynomial expression:
(y + 5)²
(y - 5)(y + 5)
Let's simplify each of the given expression:
a.) (y + 5)²
The given equation is a factor of a perfect square trinomial. For this type of expression, the following is the formula for expanding it.
We get,
b.) (y - 5)(y + 5)
To be able to simplify the following expression. We will be using the formula for the difference of two squares.
We get,
