Solving Quadratics (Monic)

1)\(x^2 +5x + 6=0\)
\(x=-2 \quad or \quad x= -3\)
2)\(x^2+2x-15=0\)
\(x=3\quad or\quad x=-5\)
3)\(x^2-5x+6=0\)
\(x=6 \quad or \quad x=-1\)
4)\(x^2-2x+15=0\)
\( x=5 \quad or \quad x=-3\)
5)\(x^2-8x-9=0\)
\(x=9 \quad or \quad x= -1\)
6)\(x^2-6x+9=0\)
\(x=3\)
7)\(x^2 -12x+35=0\)
\(x=7 \quad or \quad x=5\)
8)\(x^2-8x-65=0\)
\(x=13 \quad or \quad x=5\)
