Answer 2

Answer:

Question :-

x = -2 then, find the x³-x²+x+2

Required Answer :-

-12 is your answer

Solution :-

Substitute x = -2 in the equation x³-x²+x+2

${x}^{3} - {x}^{2} + x + 2$

$= {( - 2)}^{3 } - {( - 2)}^{2} + ( - 2) + 2$

$= (- 8) - (4) - 2 + 2$

$= - 8 - 4 - 2 + 2$

$= - 8 - 4 -\cancel 2 \: + \cancel2$

$= - 8 - 4$

$= - 12$
