Answer 4

noo not right

Answer 5

and x=1/2(3-sqrt5)

Answer 6

it is :P

Answer 7

i about to draw the answer choices

Answer 8

the answer should be x= 3+/-sqrt13/2

Answer 9

If ax^2 +bx +c =0 is the quadratic equation then the solution for x is
x={-b±√(b^2 -4ac)} /(2a)
Now for the given equation a=1, b=-3, c=-1 so
x={-(-3)±√((-3)^2 -4(1)(-1))} /(2*1)
..={+3±√(9 +4))} /2
..={3±√13}/2
So the solution set is
{3+√13}/2, 3-√13}/2}
