Let p(x) = x3 + 13x2+ 32x + 20
p(-1) = (-1)3 + 13(-1)2 + 32(-1) + 20
= -1 + 13 - 32 + 20 = 0
∴ By Factor Theorem, x - (-1), i.e., (x + 1) is a factor of p(x).
x3 + 13x2 + 32x + 20
= x2(x + 1) + 12x(x + 1) + 20(x + 1)
= (x + 1)(x2 + 12x + 20)
= (x + 1)(x2 + 2x + 10x + 20)
= (x + 1){x(x + 2) + 10(x + 2)}
= (x + 1)(x + 2)(x + 10).

(3x+4y)(8x-3y)
= 3x (8x - 3y) + 4y (8x - 3y)
= 24x2 - 9xy + 32xy - 12y2
= 24x2 + 23xy - 12y2

101 × 99
= (100 + 1) (100 - 1)
= (1002 - 12 ) (because a2 - b2 = (a - b) (a+b))
= 10000 - 1
= 9999

Polynomials = Poly (means many) + nomials (means terms). Thus, a polynomial contains many terms
Thus, a type of algebraic expression with many terms having variables and coefficients is called polynomial.
Example: 3x , 5y2+2x+5, and 2x2+2
