Chapter 8.2, Problem 81SR

To determine

To solve: the equation and state the type of root.

Answer to Problem 81SR

The value of equation is $x=-\frac{8}{3}$ and the root is real number.

Explanation of Solution

Given information:

The equation is $3x+8=0$ .

Calculation: to solve the equation, first subtract and then divide then simplify,

  $\begin{array}{l}3x+8=0\\ 3x=-8\text{ [subtract 8 from both side]}\\ x=-\frac{8}{3}\text{ [divide]}\end{array}$

Thus, the root of the equation is $x=-\frac{8}{3}$ and the root is real number.
