Question

please solve the question​

Answer 1

using (a-b)²=a²+b²-2ab in (3x-1)²

= (3x)²+(1)²+2(3x)(1)

= 9x²+1+6x

now using (x+a)(x+b)=x²+ab+b²in (3x-2)(3x+1)

= (3x)²+(-2)(1)+(-2)²

= 9x²-2+4

= 9x²+2

now

9x²+1+6x-(9x²+2)

= 9x²+1+6x-9x²-2

= 6x-1

I do only that much question

bcz u don't say what is want to do in question

if this is right

plz mark it as brainliest
