Answer 1

Answer:

1.=(2x+7) (3x+1)

2.=(x+2) (7x-2).

Step-by-step explanation:

1.

6x^2+23x+7. (middle term factorization).

=6x^2+(21+2)x+7 ("^"= square)

=6x^2+21x+2x+7

=3x(2x+7)+1(2x+7)

=(2x+7) (3x+1)

2.

7x^2+12x-4. (middle term factorization).

=7x^2+(14-2)x-4 ("^"= square)

=7x^2+14x-2x-4

=7x(x+2)-2(x+2)

=(x+2) (7x-2).
