Step-by-step explanation:
Think about it both of the sides of the triangle are the same, so that would mean two of the degrees would be the same
Quadratic Formula is (-b ±√(b²-4ac))/2a
With that being said:
y=2x²-5x-1 is in the correct form of ax²+bx+c
Now just plug in:
5±√(25-4(2 x-1))
5± √25+8
(5±√33)/2(2)
Answer is D
100% Sure
