Question

p(x)=x²–81 ,Find the zeros of the given quadratic polynomial.

Answer 1

two solution are enough to find.
hope it will helps U.......

Answer 2

Solution :

Given p(x) = x² - 81

Let p(x) = 0

=> x² - 81 = 0

=> x² - 9² = 0

=> ( x + 9 )( x - 9 ) = 0

x + 9 = 0 or x - 9 = 0

x = -9 or x = 9

Therefore ,

-9 , 9 are two zeroes of given

quadratic polynomial p(x).
