Answer: second option

Step-by-step explanation:

The standard form of a quadratic equation is:

$ax^2+bx+c=0$

Then, to write the quadratic equation given in the problem in standard form, you must substract 1 from both sides of the equation. Then you have:

$2x^2+5x-1=0$

Given the quadratic equation above, to find the value of $b^2-4ac$ you must substitute:

a=2; b=5 and c=-1 into $b^2-4ac$

Thenrefore, you obtain the following result:

$5^2-4(2)(-1)=33$
