The correct answer is the value of p is -2 and r is -2.
Given: Factors of equation = y-2 and .
Equation = .
To Find: The value of p and r.
Solution:
If y-2 and are the factors of . Then their multiplication should be equal to the equation.
= (y - 2)(y - )
=
= 0
Multiply the equation by -2. As the RHS is 0 it will not effect the equation.
= 0
= 0
= 0
Now compare both the equations.
By comparing coefficient of .
p = -2
By comparing constants.
r = -2
Hence, the value of p is -2 and r is -2.
