Answer:
Step-by-step explanation:
x² + 29x - 30
Product = -30
Sum = 29
Factor = 30 * (-1)
x² + 30x - 1x - 30 = x*(x + 30) -1*(x +30)
= (x + 30) (x - 1)
We can't find explicit values for 
and 
, since there is only one equation, but two variables.
The best we can do is solve for one variable with respect to the other:
Solve for :
subtract 
from both sides:
divide both sides by 
:
Solve for :
subtract 
from both sides:
divide both sides by 
:
