Hi

using the quadratic equation to solve

9t^2+6t=1

9t^2+6t- 1 = 0

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

x+=+%28-6+%2B-+sqrt%28+72+%29%29%2F%2818%29+

x+=+%28-6+%2B-+sqrt%28+36%2A2+%29%29%2F%2818%29+

x+=+%28-6+%2B-+6%2Asqrt%282%29%29%2F%2818%29+

x+=+highlight%28-1%2F3+%2B-+%281%2F3%29%2Asqrt%282%29%29
