Answer:
-2.77778°C
Step-by-step explanation:
(27°F − 32) × 5/9 = -2.778°C
In quadratic equations,
a + b = -B
ab = C
where a and b are the roots, B is the second term, and C is the constant.
Substituting,
a + b = -12
ab = 35
The values of a and b from the equation is -7 and -5. Thus, the lesser root is -7.
