Hi,

Solve using quadratic formula: 

6x^2 + 7x - 11 = 0

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

x+=+%28-7+%2B-+sqrt%28+49+-4%2A66+%29%29%2F%2812%29+   || Yes. Good Work.  Keep going...

x+=+%28-7+%2B-+sqrt%28+49+%2B+264+%29%29%2F%2812%29+

 x+=+%28-7+%2B-+sqrt%28313+%29%29%2F%2812%29+ Leave in this format

 x+=+%28-7+%2B-+17.6918%29%2F%2812%29+  or use your calculator
