x²+5670x+153 = 0

a=1, b=5670, c=153

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

x+=+%28-5670+%2B-+sqrt%28+5670%5E2-4%2A1%2A153+%29%29%2F%282%2A1%29+

x+=+%28-5670+%2B-+sqrt%2832148900-612+%29%29%2F2+

x+=+%28-5670+%2B-+sqrt%2832148900-612+%29%29%2F2+


x+=+%28-5670+%2B-+sqrt%2832148288%29%29%2F2+

x+=+%28-5670+%2B-+sqrt%28576%2A55813%29%29%2F2+

x+=+%28-5670+%2B-+sqrt%28576%29sqrt%2855813%29+%29%2F2+

x+=+%28-5670+%2B-+24%2Asqrt%2855813%29%29%2F2+

x+=+%28-5670+%2B-+24%2Asqrt%2855813%29%29%2F2+

x+=+%282%28-2835+%2B-+12%2Asqrt%2855813%29%29%29%2F2+

x+=+%28cross%282%29%28-2835+%2B-+12%2Asqrt%2855813%29%29%29%2Fcross%282%29+

x+=+-2835+%2B-+12%2Asqrt%2855813%29+

Using the + and a calculator:  x = -.0269842554

Using the  and a calculator:  x = -.5669.973016
