Answer:

Special Product

1. Product of a Binomial and a Trinomial

2. Cube of Binomial

General Formula

1. ( a + b ) ( c + d )

= ac + ad + bc + bd

2. ( a + b ) ( a - b )

= a² - b²

3. ( a + b + c )²

= a² + b² + c² + 2ab + 2ac + 2 bc

Example with answer

1. ( x + 3) ( x + 5 )

= x² + 5x + 3x + 15

= x² + 8x + 15

2. ( x + 5 ) ( x - 5 )

= (x)² - (5)2

= x² - 25

3. ( x + 2y + 3z)²

= x2 + 4y² + 9z² + 4xy + 6xz + 12 yz

4. ( x + 3 ) ( x² - 3x + 9 )

= (x)3 + (3)3

= x³ + 27

5. ( x + 5)³

= x³ + 3(x)²(5) + 3(x)(5)² + (5)³

= x³ + 15x² + 75x + 125
