#### Solutions

Chapter 1.4, Problem 8E
To determine

## To calculate: the domain of the expression 2t2−53t+6 .

Expert Solution

The domain of the given expression is tR{2}

Where R is real number

### Explanation of Solution

Given information:

The given expression is provided below

2t253t+6

Formula used:

The denominator part of the expression does not be 0 .

Calculation:

Consider the expression as,

2t253t+6

Recall that the denominator should not be equal to 0

Therefore

3t+603t6t2

So the domain part of the expression will not contain t=2 because if it contain then the given expression will does not exist.

The domain of the expression 2t253t+6 is

R{2}

Where R belongs to real number
