Answer: x=1 or x=-3
Step-by-step explanation:
Quadratic formula is [tex]-b+-\sqrt{b^{2}-4ac } /2[/tex]
a=1 b=2 c=-3
Substitute
[tex](-2+-\sqrt{2^{2}-4(1)(-3) }) /2\\(-2+-\sqrt{4+12}) /12\\(-2+-\sqrt{16}) /2\\(-2+-4) /2\\x=\frac{-2+4}{2} \\x=\frac{-2-4}{2} \\\\\\Simplify\\x=\frac{2}{2} \\\\x=\frac{-6}{2} \\\\Simplify\\x=1\\x=-3[/tex]
