Question

find the value of the polynomial p(-1) for the value of the variables of x³-5x²+2x+7​

Answer 1

Answer:

$given \: expression \\ \\ {x}^{3} - 5 {x}^{2} + 2x + 7 \\ \\ so \: p( - 1) \\ \\ = ( - 1) ^{3} - 5( { - 1})^{2} + 2( - 1) + 7 \\ \\ = - 1 - 5(1) + ( - 2) \\ \\ = - 1 - 5 - 2 \\ \\ = - 6 - 2 \\ \\ = - 8$

Answer 2

Answer:

the answer is -1

Step-by-step explanation:

taking p(x) = x3-5x2+2x+7

p(-1) = after evaluvation

-1-5-2+7

answer is -1 .
