Question

Answer two questions about the following rational expression.

x² - 4x + 4/
22 + 5x – 14
1. What is an equivalent expression in lowest terms?
X-2
x + 7
2. What values of a must we exclude from the domains of the expressions?

Answer 1

Is the expression (22 + 5x – 14) correct?

Explanation:

(x² - 4x + 4)/(22 + 5x – 14)

This makes little sense to me: The denominator reduces to (5x + 8).

(x² - 4x + 4)/(5x + 8)

I don't know if this can be reduced any further.

X cannot be anything that would cause the denominator to become 0.

0 = (5x + 8)

x = -(8/5)

x cannot be - (8/5)

Please check the equation and see if (22 + 5x – 14) is correct.
