You can put this solution on YOUR website!
The quadratic solver equation is: x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
Where a= the amount of x squared's
b= the amount of x's
c= the number added on the end
So: a=1,
b=-2,
c=2
Using the equation given:
x+=+%282+%2B-+sqrt%28+2%5E2-8+%29%29%2F%282%29+
x+=+%282+%2B-+sqrt%28+-4+%29%29%2F%282%29+
x+=+%282+%2B-+2+sqrt%28+-1+%29%29%2F%282%29+
x+=+%281+%2B-+sqrt%28+-1+%29%29+
So x=1+i or x=1-i,
where "i" is the imaginary number sqrt%28-1%29
I hope this helps.
P.S. I am trying to start my own mathematics homework help website. I would be extremely grateful if you would send me your feedback on my help to adam.chapman@student.manchester.ac.uk.
