Question

Use suitable identities to find the following Products

(3-2x)(3+2x)​

Answer 1

Step-by-step explanation:

(3-2x) (3+2x)

By the identity,

(a+b) (a-b) = a^2-b^2

a= 3, b= 2x

now,

substituting the values in the identity,

a^2-b^2= (3) ^2-(2x) ^2

= 9- 4x^2

hope this helps! ❤

Answer 2

Answer:

(3-2x)(3+2x)

(a-b)(a+b) = a²-b² {identity}

(3)² - (2x)²

9 - 4x²
