%2811x-50%29%5E2=70

%2811x%29%5E2-2%2A%2811x%29%2A50%2B50%5E2=70

121x%5E2-1100x%2B2500-70=0

121x%5E2-1100x%2B2430=0....use quadratic formula to solve for x

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

x+=+%28-%28-1100%29+%2B-+sqrt%28%28-1100%29%5E2-4%2A121%2A2430+%29%29%2F%282%2A121%29+

x+=+%281100+%2B-+sqrt%281210000-1176120+%29%29%2F242+

x+=+%281100+%2B-+sqrt%2833880+%29%29%2F242+

x+=+%281100+%2B-+184.065%29%2F242+

solutions:

x+=+%281100+%2B+184.065%29%2F242+

x+=+1284.065%2F242+

x+=+5.3+
or
x+=+%281100+-184.065%29%2F242+

x+=+915.935%2F242+

x+=+3.8+
