Question

the value of x³ - x² + x - 1 for x = -1​

Answer 1

${x}^{3} - {x}^{2} + x - 1$

Substitute -1 in the terms of x

$( { - 1})^{3} - ( { - 1})^{2} + ( - 1) - 1$

$( - 1 \times - 1 \times - 1) - ( - 1 \times - 1) + ( - 1) - 1$

$( - 1) - ( - 1) + ( - 1) - ( - 1)$

$( - 1) + (1) - (1) + ( -1 )$

$- 1 + 1 - 1 + 1 = 0$
