I don’t think anyone knows this one not even James
2x2−5x=3
I think the first step would be to
Subtract 3 from both sides
2x2−5x−3=3−3
2x2−5x−3=0
Then
For this equation: a=2, b=-5, c=-3
2x2+−5x+−3=0
Lastly you would
Use quadratic formula with a=2, b=-5, c=-3
I think your answer would then have to be...
x = 3 or x = −1
/2
Answer:
2
Step-by-step explanation:
I found this be adding 4 and 6, witch is 2.
X=
Or it would be approximately: x≈ 0.37228132, -5.37228132
Hope this helped! ;P
