Answer:
x = +5, -5
Step-by-step explanation:
Given,
p(x) = x^2 - 25
Since, it is a quadratic equation, thus it will have two zeroes that is 'α' and 'β'.
Then,
x^2 - 25 = 0
=> x^2 = 25
=> x = +/- √25 = +/- 5
=> x = +5, -5
For the values of x :
x = + 5 ( α )
x = -5 ( β )
VERIFICATION :
Here, a = 1 , b = 0 , c = 25
We know that,
i) α + β = -b/a
=> +5 - 5 = 0/1
=> 0 = 0
LHS = RHS
Hence, verified
ii) α × β = c/a
=> (5) × (-5) = -25/1
=> -25 = -25
LHS = RHS
Hence, verified.
