30x%5E2+%2B+11x+-+30+=+0
Use the quadratic formula
a=30
b=11
c=-30
x+=+%28-11+%2B-+sqrt%28+11%5E2-4%2A30%2A%28-30%29+%29%29%2F%282%2A30%29+
x+=+%28-11+%2B-+sqrt%28+121%2B3600+%29%29%2F%2860%29+
x+=+%28-11+%2B-+sqrt%28+3721+%29%29%2F%2860%29+
x+=+%28-11+%2B-+61+%29%2F%2860%29+

x%5B1%5D=%2850+%29%2F%2860%29+
x%5B1%5D=5%2F6+
