5c3 – 6c2 – 2c ; c = −5

Sure, let's solve the equation step by step.

The equation is: 5c^3 - 6c^2 - 2c, and we are given that c = -5.

Step 1: Substitute c = -5 into the equation.

= 5(-5)^3 - 6(-5)^2 - 2(-5)

Step 2: Simplify the equation.

= 5(-125) - 6(25) + 10

= -625 - 150 + 10

Step 3: Add the numbers together.

= -765

So, 5c^3 - 6c^2 - 2c equals -765 when c equals -5.
