Given x = -1 ,
Equation : f(x) = x³ - 8x² + 14x - 7
Substitute x = -1
f( -1 ) = (-1)³-8(-1)²+14(-1) -7
= -1 -8(1)-14-7
= -1 -8 -14 - 7
= -30
Therefore , Value of x³ - 8x² + 14x - 7 is -30 when x = -1

= -1 -8(1)-14-7
= -1 -8 -14 - 7
= -30

Given that,
x = -1 ,
p(x) = x³ - 8x² + 14x - 7
p (-1 ) = (-1)³- 8(-1)² + 14(-1) - 7
= -1 -8(1)-14-7
= -1 -8 -14 - 7
= -30
Hence,
-30 is the Required answer...
