• Polynomial - power of the variable with some operations.

• An algebraic expression of the type p(x) = $\large \sf \red{a_0 , a_1 , a_2 ... a_n}$ are constant terms and power of X is a non negative integer is called a polynomial in x or y.

• It is always denoted by p(x) , p(y) , p(t) , q(t) , f(x) , f(y)

• Example - p(x) = 5x⁴ + 3x² - 2x + 5
• p(t) = t⁴ + t² + 3
