Answer: second optionStep-by-step explanation: The standard form of a quadratic equation is:[tex]ax^2+bx+c=0[/tex] 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: [tex]2x^2+5x-1=0[/tex] Given the quadratic equation above, to find the value of [tex]b^2-4ac[/tex] you must substitute: a=2; b=5 and c=-1 into [tex]b^2-4ac[/tex] Thenrefore, you obtain the following result: [tex]5^2-4(2)(-1)=33[/tex]
