Hi

Using the quadratic formula to solve  

3x^2 -7x – 2 = 0   |Note use of ^  (uppercase 6)

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

x+=+%287+%2B-+sqrt%28+73%29%29%2F%286%29+



4x^2 =7-2x

4x^2 + 2x - 7 = 0 

x+=+%28-2+%2B-+sqrt%28116%29%29%2F%286%29+

x+=+%28-2+%2B-+sqrt%284%2A29%29%29%2F%286%29+

x+=+%28-2+%2B-+2%2Asqrt%2829%29%29%2F%286%29+
