Question from Lorrie, a student: x^2/5 - 4/5 = -3/5x |
Lorrie,
When I look at the equation
the first thing I notice is all the fractions. I would rather not deal with fractions so I would like to eliminate them. Fortunately they all have a denominator of 5 to I can eliminate them by multiplying both sides of the equation by 5. This gives
x2 - 4 = -3 x
Now add 3x to each side to obtain
x2 +3 x - 4 = 0
Can you factor this and solve for x?
