Question

Which of the following general formula of special products is TRUE?

A. (a²-ab+b²)(a+b)=a³-b³
B. (a-b)(a+b)=(a²+b²)
C. (a²+ab+b²)(a-b)=a³+b²
D. (a+b)(a-b)=(a²-b²)

Answer 1

The correct general formula of special products is (a+b)(a-b)=(a²-b²).

Step-by-step explanation:

The correct general formula of special products is:

(a+b)(a-b)=(a²-b²)

This formula is known as the difference of squares. It states that when we multiply the sum and difference of two quantities, we get the difference of their squares.

For example, if we have the expression (a+b)(a-b), we can expand it using the distributive property to get a² - b².
