Best ResponseYou've already chosen the best response.0ok look my teacher gave us some equations and one of them are \[{x}^2+6x+9=0\] and the answeres are x=3 so i dont get it

Best ResponseYou've already chosen the best response.0yes, this is (x+3)^2 so x = 3

Best ResponseYou've already chosen the best response.0ok ;) so how do iget the answer for the first one

Best ResponseYou've already chosen the best response.0Take the coefficient of the terms: i.e. the function is in ax^2+bx+c=0 form and plug the values of a, b, and c into the formula myiniaya posted, that is one way.

Best ResponseYou've already chosen the best response.0the first one is \[x=b \pm \sqrt{b ^{2} 4ac} \div 2a\] ;D

Best ResponseYou've already chosen the best response.0we can solve it for b, a, or c? its already solved for x

Best ResponseYou've already chosen the best response.0well yeah the teacher wants us to find all thee a b and c but i dont reallly know how!

Best ResponseYou've already chosen the best response.0she wants you to solve the quadratic formula for a then b then c are you sure?

Best ResponseYou've already chosen the best response.0k let's see if we can do it let's try to solve for a first

Best ResponseYou've already chosen the best response.0it is impossible to solve this equation for a b and c

Best ResponseYou've already chosen the best response.0i think you can use the quadratic formula to solve for a lol

anonymous

Best ResponseYou've already chosen the best response.0yes, but it impossible to solve for all three values of a,b and c

Best ResponseYou've already chosen the best response.0lol. i honestly don't think this what your teacher wants

Best ResponseYou've already chosen the best response.0i can solve for b and c use the quad on b and c is easiest

Best ResponseYou've already chosen the best response.0no, you cannot. x can hold only two values. you need atleast 3 equations to solve for 3 unknown variables.

Best ResponseYou've already chosen the best response.0a doeesnt have to be both it can be one or the other just like x

anonymous

Best ResponseYou've already chosen the best response.0you may be able to get a,b and c in terms of the other variables, but that doesn't get you any closer to solving for them.

Best ResponseYou've already chosen the best response.0right but it sounded like he wanted us to solve the quadratic formula for each lol

Best ResponseYou've already chosen the best response.0oh, that is just an exercise in stupidity.

anonymous

Best ResponseYou've already chosen the best response.0there is no point of that. I don't think their teacher asked them to solve for a,b and c.
