Find the Constants a and B So That the Two $x ^ { 2 }$

Find the constants A and B so that the two polynomials are equal. (Hint: Create a system of linear
equations by equating the constant terms and by equating the coefficients on the x terms and $x ^ { 2 }$ terms.)
- $- 16 x ^ { 2 } + 10 x - 6 = - 2 A x ^ { 2 } - A x + 5 A - 6 B x ^ { 2 } + 6 B x - 3 B + 6 C x ^ { 2 } + 3 C x - 5 C$

A) $\{ ( 5,2,1 ) \}$
B) $\{ ( - 1 , - 1,5 ) \}$
C) $\{ ( - 1 , - 4 , - 7 ) \}$
D) $\{ ( - 1,2 , - 1 ) \}$
