Quadratic formula \[x=b \pm \sqrt{b^24ac}/2a\]
 one year ago

nubeerBest ResponseYou've already chosen the best response.0
\[x = \frac{ b \pm \sqrt{b ^{2}4ac } }{ 2a}\] this is the quadratic formula now look at your equation it's x^29x+20 so a =1 ,b = 9 , c = 20 just plug in values you will get 2 values of x

that is so confusing

yes  you asked about factoring quadratics factor to the form (x +/ a)(x +/ b)

cwrw238Best ResponseYou've already chosen the best response.1
to find a and b you need the product ad = +20 and sum = 9 can u think of 2 numbers which fit this requirement?

hba  your method is slightly different to mine  true

I am talking about the answer she got ?

cwrw238Best ResponseYou've already chosen the best response.1
oh yes  i misread it (x  4)(x  5) is correct solution a = 4 and b = 5 raee_009
