Question

(2x-1)^2-(4x-1)(x-3)

Answer 1

\(\left(2x-1\right)^2-\left(4x-1\right)\left(x-3\right)=4x^2-4x+1-4x^2+13x-3=9x-2\)

Answer 2

\(\left(2x-1\right)^2-\left(4x-1\right)\left(x-3\right)\)

\(=4x^2-4x+1-4x^2+12x+x-3\)

\(=9x-2\)

Answer 3

=((2x)^2-2/2x/1+1^2)-(4x-1)(x-3)

=(4x^2-4x+1)-(4x^2-9-x)

=4x^2-4x+1-4x^2+9+x

=-3x+10
