Question

Using suitable identity find the product of (3x -1/3) (3x-1/3)​

Answer 1

Answer:

Step-by-step explanation:

Suitable Identity=(a-b)^2=a^2+b^2-2ab

(3x-1/3)(3x-1/3)=(3x-1/3)^2

                           (3x)^2+(1/3)^2-2*3x*1/3

                           9x^2+1/9-2x

Answer 2

its very simple!!

we know that multiplying 2 numbers means taking its square. that's what we did here

then we put the formula

(a-b)² =a²+b²-2ab

and solve them

hope this helps you☺️☺️
