Best ResponseYou've already chosen the best response.2\[x^212x+36\] \(a=1,b=12,c=36\) then use the quadratic formula \[x=\frac{(b)\pm\sqrt{(b)^{2}4(a)(c)}}{2a} \]

Best ResponseYou've already chosen the best response.3Why can;t we just factor this by the way?? :o \(x^2  6x  6x +36\) \(=x(x6)6(x6)\) \(=(x6)^2\)

Best ResponseYou've already chosen the best response.2yeah lol. \(x^212x=36\) => \(x^212x+36\) \(a+b= 6+6\) \(a*b=6*6\) you can justuse the quadratic formula anyway; its faster.
