Use suitable identities to find the following products| Polynomials | Ex 2.5 class 9 [Q1]

Exercise 2.5 class 9
1. Use suitable identities to find the following products:
(i) (x + 4) (x + 10) [0:13]
(ii) (x + 8) (x – 10) [1:02]
(iii) (3x + 4) (3x – 5) [2:02]
(iv) (y2 + 3/2 ) (y2 – 3/2) [3:35]
(v) (3 – 2x) (3 + 2x) [4:52]

Note:
Question is taken from NCERT class 9 maths
Identities 📝:
(x+a)(x+b) = x^2 + (a+b)x + ab
(a+b)(a-b) = a^2 – b^2
