Question

Using indentity (2x + 1 ) (3x - 2 )

step by step explanation plz​

Answer 1

Answer:

The answer for (2x + 1 ) (3x - 2 ) is  $6x ^{2} -x-2$

Step-by-step explanation:

$(2x+1)(3x-2)$

We can write this in the form

$(2x+1)((2x+x-2)$

let

          $a=2x\\ b=1\\ c=x-2$

We can use the identity ,

       $(a+b) (a+c)=a^{2} +(b+c)a+bc$

putting the value in the above equation ,

  =$(2x)^{2}+(1+x-2)2x+1(x-2)\\ \\ 4x^{2} +(x-1)2x+(x-2)\\ \\ 4x^{2}+2x^{2}-2x+x-2\\ \\ 6x^{2}-x-2$
