7x%5E2%2B3x%2B8=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+ ....a=7, b=3 and c=8

x+=+%28-3+%2B-+sqrt%28+3%5E2-4%2A7%2A8+%29%29%2F%282%2A7%29+

x+=+%28-3+%2B-+sqrt%28+9-224+%29%29%2F14+

x+=+%28-3+%2B-+sqrt%28+-215+%29%29%2F14+

x+=+%28-3+%2B-+14.7i%29%2F14+

x+=+-3%2F14+%2B-+14.7i%2F14+

x+=+-0.214+%2B-+1.05i+.......means, there is no real solutions, only

complex solutions:

x+=+-0.214+%2B+1.05i+
or
x+=+-0.214+-+1.05i+
