Best ResponseYou've already chosen the best response.2alright zeros(solutions , xintercept) you can use quadratic formula `OR` you can factor it

Best ResponseYou've already chosen the best response.2ohh well nvm you have to apply the quadratic formula \[\huge\rm x=\frac{ b \pm \sqrt{b^24ac} }{ 2a }\]

Best ResponseYou've already chosen the best response.2ax^2+bx+c quadratic equation where a=leading coefficient b=middle term cconstant term so what is a b and c in that equation ?

Best ResponseYou've already chosen the best response.2\(\huge\color{reD}{\rm b^24ac}\) `Discriminant` you can use this to find if the equation is factorable or not if ` b^24ac > 0` then there are 2 real zeros if ` b^24ac = 0` then there is one real root if ` b^24ac < 0` then you will get two complex roots (no xintercept)

Best ResponseYou've already chosen the best response.2i mean convert 3x^2 +4x+12 into y=a(xh)^2+k <(vertex form) b using completing the square method :=)

Best ResponseYou've already chosen the best response.0so it would be 3x^2+(4x/2)^2+......+12..... (3x^2+4x+4)+124 (3x+2)^2+8 is this correct

Best ResponseYou've already chosen the best response.2okay you need to complete the square of (3x^2+4x) it would be great if you take out the 3
