Evaluate each expression if $a = 鈭� 1, 鈥� b = 4, 鈥刟苍诲 c = 6$ .
36. $3 a 鈭� 4 a^{2} + 2 a$

Short Answer

Expert verified

The value of the expression is $鈭� 5$ .

Step by step solution

– Write the given information

The expression given is

$3 a 鈭� 4 a^{2} + 2 a$

And

$a = 鈭� 1, b = 4 and c = 6$

- DESCRIPTION OF STEP

To solve the given expression substitute variable a by $- 1$ , as:

$3 a 鈭� 4 a^{2} + 2 a = 3 (鈭� 1) 鈭� 4 {(鈭� 1)}^{2} + 2 (1)$

Simplify the above as:

$\begin{matrix} 3 (鈭� 1) 鈭� 4 {(鈭� 1)}^{2} + 2 (1) = 鈭� 3 鈭� 4 (1) + 2 \\ = 鈭� 1 鈭� 4 \\ = 鈭� 5 \end{matrix}$

Thus, $3 a 鈭� 4 a^{2} + 2 a = 鈭� 5$ .
