Question

thực hiện phép nhân

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

Answer 1

\(4x(3x-1)-2(3x+1)-(x+3)\)

\(=12x^2-4x-6x-2-x-3\)

\(=12x^2-11x-5\)

Answer 2

`4x(3x-1)-2(3x+1)-(x+3)`

`= 12x^2 - 4x - 6x -2 -x -3`

`= 12x^2 +(-4x-6x-x)+(-2-3)`

`= 12x^2 -11x -5`

Answer 3

\(=12x^2-4x-6x-2-x-3=12x^2-11x-5\)

Answer 4

.................................????????????????????

Answer 5

...........????????nooooooooooooooooooooooo

Answer 6

$4x(3x-1)-2(3x+1)-(x+3)$

$=12{}^{}-4x-6x-2-x-3$

$=12{}^{}-11x-5$

Answer 7

4x(3x−1)−2(3x+1)−(x+3)

=12x2−4x−6x−2−x−3

=12x2+(−4x−6x−x)+(−2−3)

=12x2−11x−5
