Answer:
49
Step-by-step explanation:
In the quadratic formula, the expression under the sign of the square root, [tex]b^{2}-4ac[/tex], is called the discriminant.
[tex]x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}[/tex]
So we replace each term and find the discriminant:
[tex]a=2\\b=3\\c=-5\\discriminant=3^{2} -4(2)(-5)=9+40=49[/tex]
