Question

p (x) = p ( 2 ) 2x³ + x² -2x -1 ​

Answer 1

$p (x) = p ( 2 ) = 2x³ + x² -2x -1 \\ solution. \\ = 2(2) {}^{3} + (2) {}^{2} - 2(2) - 1 \\ = 2(8) + 4 - 4 - 1 \\ = 16 + 4 - 5 \\ = 20 - 5 \\ = 15 \: \: answer...$

Answer 2

Answer:

$p(x) = 2 {x}^{3} + {x}^{2} - 2x - 1 \\ p(2) = 2 {(2)}^{3} + {(2)}^{2} - 2(2) - 1 \\ = (2 \times 8) + (4) - (2 \times 2) - 1 \\ = 16 + 4 - 4 - 1 \\ \large{ \boxed{= \underline{ \underline{15}}}}$
