Pls help picture provided

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

X2 + y2 - 14x + 10y + 65 = 0 <br><br> will lie ENTIRELY in Quadrant
Afina-wow [57]
Rearranging to standard form 
= (x - 7)^2 + (y + 5)^2 = -65 + 49 + 25
 (x-7)^2 + (y+5)^2 = 9 
so the centre is at (7,-5) and the radius is 3

so the circle will be entirely in Quadrant 4.
