Question

Factorize the following :- 49c square -25d square​

Answer 1

Answer:

49c² - 25d² = (7c + 5d) (7c - 5d)

Step-by-step explanation:

Given,

49c² - 25d²

= (7c)² - (5d)²

as we know , x² - y² = (x + y) (x - y)

so,

(7c)² - (5d)² = (7c + 5d) (7c - 5d)

Hence, 49c² - 25d² = (7c + 5d) (7c - 5d)
