Label the squares and rectangles in Fig 4.4 so that it represents the identity Class 9

Question 1.

Label the squares and rectangles in Fig 4.4 so that it represents the identity Class 9

(a+ b + c)² = a² + b² + c² + 2ab + 2bc + 2ca.

Answer:

Till now, we have verified the following three algebraic identities and used them for calculations and manipulation of algebraic expressions:

i. (a + b)² = a² + 2ab + b²

ii. (a - b)² = a² - 2ab + b²

iii. (a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ca
