faiqraees · Answer

apply the quadratic formula

ltrout · Answer

@FaiqRaees Could you provide an example using the first problem and I'll try it on the second?

faiqraees · Answer

General form of a quadratic 
$$\large\rm ax^2 + bx+c = 0$$
$$\large\rm x = \frac {-b \pm \sqrt{b^2-4ac}}{2a}$$

faiqraees · Answer

Can you apply it?

ltrout · Answer

@FaiqRaees So I should first change the problems to fit the ax^2+bx+c = 0 correct?

foreveralone01 · Answer

^the ax^2+bx+c=0 is how you should set it up. Sorry if that didn't make any sense. So just insert your equation

ltrout · Answer

So I just leave the 4x^2=-4x-1 like it is?

foreveralone01 · Answer

Yep

ltrout · Answer

But then there isn't a C on either side? This is confusing.

foreveralone01 · Answer

True and hold on give me a sec

faiqraees · Answer

no arrange it

faiqraees · Answer

in that way you would know what will be the values of a b and c

foreveralone01 · Answer

Okay just go with what they're saying because I'm not making sense lol
