Question

Find the value of x^3- 2x²+7x - 6 if (x=2)​

Answer 1

Step-by-step explanation:

${x}^{3} - 2 {x}^{2} + 7x - 6$

if x=2,

then,

${2}^{3} - 2( {2})^{2} + 7 \times 2 - 6$

$8 - 8 + 14 - 6$

$8$

Answer 2

Step-by-step explanation:

Substituting x=2 in the equation,

${2}^{3} - 2( {2}^{2} ) + 7(2) - 6 \\ = 8 - 8 + 14 - 6 \\ = 8$
