2=
H=
H=
-(-3) ± √(-3)²-4(2)(-5)
-(-3);
2
-(-3) ± √(-3)²-4(-5)
(2)
-(-3) ± √(-3)²(2)(-5)
(2)
-(-3) ± √(-3)²-4(2)(-5)
2(2)

Answer 1

-(-3) ± √(-3)^2 - 4(2)(-5) / 2(2) (the last choice).

Explanation:

Im ignoring the 2^2 in the equation

The equation transforms to

2x^2 - 3x - 5 = 0 (standard form)

So x = -(-3) ± √(-3)^2 - 4(2)(-5) / 2(2)
