Question

what are the most important 9 formula of algebra for class 8​

Answer 1

Step-by-step explanation:

Hey mate here is your answer

1. a2 – b2 = (a – b)(a + b)

2. (a + b)2 = a2 + 2ab + b2

3. a2 + b2 = (a + b)2 – 2ab

4. (a – b)2 = a2 – 2ab + b2

5. (a + b)3 = a3 + b3 + 3ab(a + b)

6. (a – b)3 = a3 – b3 – 3ab(a – b)

7. a3 – b3 = (a – b)(a2 + ab + b2)

8. a3 + b3 = (a + b)(a2 – ab + b2)

Hope it helps you !!!
