Answer:
To find the solutions to the following questions what you would need to do is to factor out the common variable or g. Which would be the following:
g(g-4) = 45
g = 45
g2 = 49
This is more of the erraneous way to find the solution for the original one factor the expression
Explanation:
g2 - 4g - 45 = 0
(g-9)(g+5) = 0
you can figure out what the 2 roots would be.
