Question

I tried doing this one but I still got it wrong and I’m not sure why

Answer 1

The value of the expression is 0

Explanation:

Given the below quadratic expression

`c^2\text{ - 5c - 5}`

According to the question, we were given c = 6

The next thing is to substitute the value of c = 6 into the expression

`\begin{gathered} (6)^2\text{ - 5(6) - 5} \\ 36\text{ - 30 - 5} \\ 5\text{ - 5} \\ =0 \end{gathered}`

The value of the expression is 0
