3x%5E2+%2B+4x+-+2+=+0
The quadratic formula works with the coefficients
for an equation of the format
ax%5E2%2Bbx%2Bc=0
For our equation, a = 3, b = 4, and c = -2
The quadratic equation is
%28-b+%2B+sqrt%28b%5E2-4ac%29%29%2F%282a%29 or %28-b+-+sqrt%28b%5E2-4ac%29%29%2F%282a%29
Working first with %28-b+%2B+sqrt%28b%5E2-4ac%29%29%2F%282a%29
%28-%284%29+%2B+sqrt%28+%284%29%5E2+-4%283%29%28-2%29%29+%29%2F%282%283%29%29
%28-4+%2B+sqrt%28+16+%2B+24+%29+%29%2F6%29
%28-4+%2B+sqrt%28+40+%29+%29%2F6%29
%28-4+%2B+2%2Asqrt%28+10+%29+%29%2F6%29
%28-2+%2B+sqrt%28+10+%29+%29%2F3%29
Working with %28-b+-+sqrt%28b%5E2-4ac%29%29%2F%282a%29 will give us
%28-2+-+sqrt%28+10+%29+%29%2F3%29
