Problem

Evaluate the expression \$4s^3 − 2s^2 + 5s + 1\$ when s = -1.

2

Step

The given expression is

\$4s^3 − 2s^2 + 5s + 1\$

3

Step

Substitute -1 in place of s in given expression

\$4(-1)^3 − 2(-1)^2 + 5(-1) + 1\$

4

Step

Simplify the expression

4(-1) - 2(1) - 5 + 1

⇒ - 4 - 2 - 4

⇒ - 6 - 4

⇒ -10

5

Solution

Therefore, when s = -1, the value of the expression \$4s^3 − 2s^2 + 5s +1\$ is -10.
