Best ResponseYou've already chosen the best response.0\[x ^{2}7x+13=0\] you can use the general solution \[x_{1}= \frac{ b+\sqrt{b ^{2}4ac} }{ 2a }\] \[x_{2}= \frac{ b\sqrt{b ^{2}4ac} }{ 2a }\] where a=1 b=7 c=13

Best ResponseYou've already chosen the best response.0so basically to solve these types of equations you just substitute and simplify with the quadratic formula?

Best ResponseYou've already chosen the best response.0It is the general method for quadratic equations (works for all the quadratic equations .. but there are some equations where you could do other methods to factoring

Best ResponseYou've already chosen the best response.0There is another way, which is completing the square, but doing the quadratic formula is fine.
