Chapter 9, Problem 4PT

To determine

To calculate:To evaluate below expression if $c=2$ and $d=-3$ -

  $c-4d^2$

Answer to Problem 4PT

The value of the expression $c-4d^2$ is $-34$ .

Explanation of Solution

Given information:

Given expression is $c-4d^2$ ; where $c=2$ and $d=-3$ .

Calculation:

Given expression is $c-4d^2$ ; where $c=2$ and $d=-3$ .

Substituting the value of c and $d$ in the above expression, we have:

  $2-4{\left(-3\right)}^2$ ,

Solving the above expression, we have:

  $\begin{array}{l}2-4{\left(-3\right)}^2\\ 2-4\left(9\right)\\ 2-36\\ -34\end{array}$

Thus, the value of expression $c-4d^2$ is $-34$ .

Conclusion:

The value of the expression $c-4d^2$ is $-34$ .
