Question

(4x+3y)(2x-3y)express as a difference of two squares

​

Answer 1

Answer:

Solution:

We can express a4 – (b + c)4 as a2 – b2.

= [(a)2]2 - [(b + c)2]2

Now we will apply the formula of a2 – b2 = (a + b) (a – b) we get,

= [a2 + (b + c)2] [a2 - (b + c)2]

= [a2 + b2 + c2 + 2ac] [(a)2 - (b + c)2]
