we literally just told you how to solve these problems in the last one. For $$f(x)=ax^2+bx+c=0$$ $x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}$Is there something you don't understand? If so just ask! We're not here to do other peoples homework for them!

$\left( x-3 \right)^{2}-3^{2}-6=0$ $\left( x-3 \right)^{2}-15=0$ $\left( x-3 \right)^{2}=15$ $\left( x-3 \right)=\pm \sqrt{15}$ $x =\pm \sqrt{15}+3$ $x =\sqrt{15}+3$ or $x =3-\sqrt{15}$
