Question

FIND THE VALUE OF THE POLYNOMIAL P(x)=x³P(x)=x³-4x²+2x+5 at x=1​

Answer 1

Answer:

Step-by-step explanation:

p(x) = x³ - 4x² + 2x +5

x = 1

p(1) = 1³ - 4*1² + 2*1 +5

      = 1 - 4 + 2 + 5

      = 8 - 4

      = 4

$\large \green{answer \: \: = \: \: 4}$

$\large \implies \green{ \underline{question}} \\ \\ \large \implies{p(x) = {x}^{3} - 4 {x}^{2} + 2x + 5 \: \: at \: \: x = 1 } \\ \\ \large \implies \green{ \underline{to \: \: find \: \: value \: \: of \: \: polynomial}} \\ \\ \large \implies{}put \: x = 1 \: \: in \: \: equation \\ \\ \large \implies{(1) {}^{3} - 4(1) {}^{2} + 2(1) + 5 } \\ \\ \large \implies{1 - 4 + 2 + 5} \\ \\ \large \implies{8 - 4 = 4}$
