Question

the factor of c^22-(5a-3b)^2 is ?
​

Answer 1

Answer:

=(5a+b)(5a-7b)

Step-by-step explanation:

a^2-b^2 =(a+b)(a-b) <(5a-3b)+4b><(5a-3b)-4b> =(5a-3b+4b)(5a-3b-4b) =(5a+b)(5a-7b)

Answer 2

Answer:

(5a – 3b)2 – 16b2

= (5a – 3b)2 – (4b)2

= (5a – 3b + 4b) (5a – 3b – 4b)

= (5a + b) (5a – 7b)
