Answer:

# 12x^2 -7x -10#

Explanation:

Multiply each term with each other

  1. #(3x) xx (4x) = 12x^2#
  2. #(3x) xx (-5) = -15x#
  3. #2 xx 4x = 8x#
  4. #2 xx (-5) = -10#

So

#12x^2 -15x +8x -10#

#12x^2 -7x -10#

Answer:

#12x^2-7x-10#

Explanation:

To multiply polynomials, you have to multiply the terms in the left by the terms on the right so multiply #3x# by #4x# and #-5# and do the same to #2#. You should get this once you're done:
#12x^2-15x+8x-10#

After you multiplied the polynomials, combine the like terms
#12x^2-7x-10#
