Answer:
The roots are rational
Step-by-step explanation:
Given
x² = 144 ( take the square root of both sides )
x = ± [tex]\sqrt{144}[/tex] = ± 12 ← both rational
A rational number can be expressed in the form
[tex]\frac{a}{b}[/tex] where a and b are integers.
12 = [tex]\frac{12}{1}[/tex] ← thus rational
- 12 = [tex]\frac{-12}{1}[/tex] ← thus rational
