1. From the title,0a+0b+3×0+c=-1, c=-12. Bring x=-5 into the original formula, b-15+(-1)=9-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a-5, a, a-5, a-5, a-5, a, a-5, a-5, a-5, a-5, a-5,

When x=-1, the algebraic equation aX5+bx3+cx-6=8, and X=1, the value of 5+bx3+cx-6 When x =-1, the algebraic equation aX5+bx3+cx-6=8, and X=1, the value of 5+bx3+cx-6

AX fifth power +bx3+cx-6=8 when x=-1
-A-b-c-6=8
A+b+c=-14
When x=1, the fifth power of ax + the third power of bx + cx-6
=A+b+c-6
=-14-6
=-20
