Best ResponseYou've already chosen the best response.2x2 + 3x – 4 = 0 Refine: 5x  4 = 0 Add 4 to both sides: 5x  4 + 4 = 0 + 4 5x=4 Divide both sides by 5: \[\frac{ 5x }{ 5 } = \frac{ 4 }{ 5 } \] Answer: \[x = \frac{ 4 }{ 5 }\]

Best ResponseYou've already chosen the best response.2The quadratic formula is (b+sqrt(b^2  4ac))/2a where ax^2+bx+c=0 a=1 b=3 c=4 substitute values and solve;

Best ResponseYou've already chosen the best response.1That is fine, I do have a couple of strategies now to use. And I do understand this. Thanks all for jumping in.

Best ResponseYou've already chosen the best response.3best way is to use common sense :) we can easily see that x=1 is a root and sum of roots is b/a =3 so 1 root is1 another will be 31=2

Best ResponseYou've already chosen the best response.3oops i did a silly mistake sum of roots ==> b/a=3 and one root is 1 so other root is 4

Best ResponseYou've already chosen the best response.1it's \[\huge\rm x^2+3x4=0\] x squared not 2x+3x :=) `squared` that's what makes it quadratic :=) just_one_last :=)

Best ResponseYou've already chosen the best response.1as suggested above factoring would be great and AC (headphone :P ) method the best!

Best ResponseYou've already chosen the best response.1Unfortunately, x2 + 3x – 4 = 0 is not a quadratic equation.
