Question

169-25y^2 Factorise using the identities(step by step) ​

Answer 1

Step-by-step explanation:

169 =13 x 13

25y²= (5y) ²

13² - 25y²

a²-b²= a+b a-b

(13 + 5y) (13-5y)

Answer 2

Answer:

(13-5y) (13+5y)

Step-by-step explanation:

using identity => a^2-b^2 = (a-b) (a+b)....

(13)^2 - (5y) ^2 = ......
