Zeroes of a polynomial p(x) is real number ‘a’ for which polynomial p(x) if p(a) = 0.
E.g.: For p(x) = x-2 , p(2) = 2-2 =0. Thus 2 is zeroes for polynomial p(x)= x-2
Note: Every real number is a zero of the zero polynomial p(x)=0.
There is no Zero for polynomial p(x)=8.
Zeroes of a polynomial is special. It is used to find factors of equation p(x)=0.

Let a,b, c are the sides of a triangle .
Given that hypotenuse(c) = 26 cm.
a + b + c = 60 cm.
∴ a + b = 60 - c = 60 - 26 =
∴ a + b = 34 --------(1)
In a right angled triangle c2 = a2 + b2
a2 + b2 = 262 = 676 ---------(2)
Now a2 + ( 34 - a)2 = 676. [ from (1)]
⇒ a2 + a2 - 68a + 1156 = 676
⇒ 2a2 - 34a + 480 = 0
⇒ a2 - 17a + 240 = 0
⇒ a2 - 10a - 24a + 240 = 0
⇒ a(a - 10) - 24(a - 10) = 0
∴ a = 10 , 24
but b = 34 - a then b = 24 , 10
∴ sides of triangle are 10 , 24.

The remainder theorem states that when a polynomial, f(x), is divided by a linear polynomial , x - a, the remainder of that division will be equivalent to f(a). The quotient remainder theorem says: Given any integer A, and a positive integer B, there exist unique integers Q and R such that. A= B * Q + R where 0 ≤ R < B. We can see that this comes directly from long division. When we divide A by B in long division, Q is the quotient and R is the remainder.

x = 3 + 2√2 ---( 1 )
1/x = 1/( 3 + 2√2 )
= ( 3 - 2√2 )/[ ( 3 + 2√2 )( 3 - 2√2 )]
= ( 3 - 2√2 )/ [ 3² - ( 2√2 )² ]
= ( 3 - 2√2 ) / ( 9 - 8 )
= 3 - 2√2 ----( 2 )
x + 1/x = 3 + 2√2 + 3 - 2√2
= 6 ----( 3 )
Now ,
do the Square of equation ( 3 ) , we get
( x + 1/x )² = 6²
x² + 1/x² + 2 = 36
x² + 1/x² = 36 - 2
= 34
