of Polynomials1. Find the result of (3x + 2) (x + 3)Solution:
(3x + 2) (x + 3) =
Method 1: Distributive Property
= 3x
(x + 3)
+ 2(x + 3)
= 3x2 + 9x + 2x + 6= 3x2 + 11x + 6
Method 2: Direct Multiplication
(3x + 2)(x + 3) =
3x2 +9x +2x + 6= 3x2 + 11x + 6
2. Find the result of (3x – 2) (2x – 6)Solution:
(3x – 2) (2x – 6) =
Method 1: Distributive Property
= 3x
(2x – 6)
– 2(2x – 6)
= 6x2 – 18x – 4x + 12= 6x2 – 22x + 12
Method 2: Direct Multiplication
(3x – 2)(2x – 6) =
6x2 –18x– 4x + 12= 6x2 – 22x + 12
