Best ResponseYou've already chosen the best response.3Should that be 10 on the far right side?

Best ResponseYou've already chosen the best response.3So it looks like this?\[\large\rm y=\frac{1}{2}x^24x10\]

Best ResponseYou've already chosen the best response.3\[\large\rm y=\frac{1}{2}x^24x+10\]Ok so like... to find yintercepts... We want to know where this function intercepts the yaxis. That happens when x=0.\[\large\rm y=\frac{1}{2}\cdot0^24\cdot0+10\]So what do you get for your xintercept? :o

Best ResponseYou've already chosen the best response.3The function will cross the xaxis when the y coordinate is zero. \[\large\rm 0=\frac{1}{2}x^24x+10\]I also don't like fractions. I would recommend multiplying both sides by 2.\[\large\rm 2\cdot0=2\cdot\left(\frac{1}{2}x^24x+10\right)\]

Best ResponseYou've already chosen the best response.3\[\large\rm 0=x^28x+20\]Do you understand what that did? :o The left side is still 0, everything on the right doubled.

Best ResponseYou've already chosen the best response.0so im gonna use that instead of 1/2??

Best ResponseYou've already chosen the best response.3I multiplied by 2 because the fraction had a 2 in the denominator. So no more fraction! Yay! Yes, use this equation instead. Do you remember how to factor and stuff? :)

Best ResponseYou've already chosen the best response.0so whatever denominator thats what your gonna multiply to get rid of fractions??

Best ResponseYou've already chosen the best response.3Yes! But if you have multiple fractions showing up in the same equation, then it becomes a little trickier. Then you would have to multiply by the Least Common Multiple of those denominators.
