Question

Check
whether (2x+1)(3x+1)=2(x-1)(x-2)
is quadratic equation or
not?​

Answer 1

Step-by-step explanation:

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

=2x.(3x+1)+1.(3x+1)=2.{x.(x-2)-1.(x-2)}

=6x^2+2x+3x+1=2.(x^2-2x-x+2)

=6x^2+5x+1=2.(x^2-3x+2)

=6x^2+5x+1=2x^2-6x+4

=6x^2-2x^2+5x+6x+1-4=0

=4x^2+11x-3=0
