Describe the error in factoring the polynomial.
6x - 7x- 3 = (3x – 3)(2x + 1)
A:Multiplication of the first terms of the two factors does not result in 6x^2
B:Multiplication of the outer terms of the two factors does not result in -7x
C:Multiplication of the outer terms and the inside terms and then addition of the products does not result in -7x.
D:Multiplication of the last terms of the two factors does not result in -3

Answer:

Th answer is C

Step-by-step explanation:

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

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

=6x²+ 3x- 6x- 3

=6x²- 3x -3

By comparing the answer to the equation given in the and in the calculculation done just above we Can see that multiplying outer terms and inside terms and then adding it, does not give -7x in any case
