Answer 2

Given:

• When x = -1 then value of the polynomial 5x+3-4x³

To find:

• Value of the polynomial 5x+3-4x³

Solution:

$: \implies \sf{5x + 3 - 4 {x}^{3} }$

• Put the value of x in the polynomial.

$: \implies \sf{5(1) + 3 - 4 {(1)}^{3} }$

$: \implies \sf{5 \times 1 + 3 - 4 {(1 \times 1 \times 1) }}$

$: \implies \sf{8 - 4}$

$: \implies   \underline{\boxed{ \frak{4}}} \pink \bigstar$

• Hence, the value of polynomial is 4
