Question

Using suitable identities, find the following
products.
(a) (4x +9y) (4x+9y)
(b)(3a^2-8b^2)(3a^2-8b^2)
(c)(3x^2/4+4y^2/7)(3x^2/4+4y^2/7)
(d) (13p-15q)(13p+15q)
........
(x+a)(x+b)=x^2+(a+b)x+(a×b) how can I use this identity for all algebraic expression. how to use identities to find product of algebraic expressions. ​
