Best ResponseYou've already chosen the best response.0when I have 3x213x10. Would you do the quadratic then?

Best ResponseYou've already chosen the best response.0it is a method to factor the quadratic equation. 3x213x10 = 0 3x215x+2x10 = 0 3x(x5)+2(x5)= 0 ,factor out x5, (x5)(3x+2)=0. so, x= 5 and x = 3/2

Best ResponseYou've already chosen the best response.0you should always see if a quadratic equation can be factored, it is much easier. If that fails, do the formula to solve
