Question

find the value of polynomial 2x - 2 x cube + 7 using the given values of x

Answer 1

$\underline{\large\bf{\mathfrak{Hello!}}}$

$Value \: of \: polynomial \: 2x - 2{x}^{3} + 7 \: \\ when \: x = 3 \\ \\ = > 2(3) - 2 {(3)}^{3} + 7 \\ \\ = > 6 - 54 + 7 \\ \\ = > 13 - 54 \\ \\ = > - 41 \\ \\ Value \: of \: polynomial \: 2x - 2{x}^{3} + 7 \: \\ when \: x = - 1 \\ \\ = > 2( - 1) - 2 {( - 1)}^{3} + 7 \\ \\ = > - 2 - 2( - 1) + 7 \\ \\ = > - 2 + 2 + 7\\ \\ = > 7 \\ \\ Value \: of \: polynomial \: 2x - 2{x}^{3} + 7 \: \\ when \: x = 0 \\ \\ = > 2(0) - 2 {(0)}^{3} + 7 \\ \\ = > 0 + 0 + 7 \\ \\ = > 7$

$\boxed{If \: x = 3 \: then \: value \: of \: polynomial = -41}$
$\boxed{If \: x = -1 \: then \: value \: of \: polynomial = 7}$
$\boxed{If \: x = 0 \: then \: value \: of \: polynomial = 7}$
