Answer: The required expand form is
33x-21x^2.

Step-by-step explanation: We are given to expand the following expression :

E=3x(11-7x)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To expand the given expression, we must multiply 3x with each of the rems within the bracket.

The expansion of expression (i) is as follows :

$E\\\\=3x(11-7x)\\\\=3x*11-3x*7x\\\\=33x-21x^2.$

Thus, the required expand form is
33x-21x^2.
