Question 51308This question is from textbook
: I am using the quadratic formula on 3x^2 = 11x + 4; 3x^2 - 11x + 4 = 0; 3x^2 - 11x - 4 = -2; I have to convert the 5.5 to a fraction, but I am confused. The answer is 1/3,-4 or the other way around (I think). I need an assist please.This question is from textbook
You can put this solution on YOUR website! I'm confused too!! You have three different quadratic equations, and I don't see how any of them relate to changing 5.5 to a fraction.
However, the first equation is
, which becomes
, which factors into
This works very well by factoring, so you don't need the quadratic formula, unless you specifically wanted to do it by quadratic formula. In this case, algebra.com has a "pluggable solver" that looks like this:
