Algebra

1. Factor if possible, - 6n^ 2 - 17 n + 14

A = - 6n^ 2 - 17 n + 14 = (2 + - 3n) (7 + 2n)

B. Polynomial is prime

2. Factor by grouping; 4y (x - z) + 7 (z - x)

= 4y (x + - 1z) + 7 (z + - 1x)

= (x * 4y + - 1z * 4y) + 7 (z + - 1x)

= (4xy + - 4yz) + 7 (z + - 1x)

= 4xy + - 4yz + 7 (- 1x + z)

= 4xy + - 4yz + (- 1x * 7 + ...
