Factories: 16a2 – 225b2 – InterviewSolution

1.	Factories: 16a2 – 225b2
Answer» We have, 16a² – 225b² = (4a)² – (15b)² By using the formula a² – b² = (a + b)(a – b) We get, 16a² – 225b² = (4a)² – (15b)² = (4a + 15b)(4a – 15b)

Factories: 16a2 – 225b2

Answer»

We have,

16a² – 225b²

= (4a)² – (15b)²

By using the formula a² – b² = (a + b)(a – b)

We get,

16a² – 225b² = (4a)² – (15b)²

= (4a + 15b)(4a – 15b)
