%28x+-+6%29+%28x+-+8%29+=+-1
Use the FOIL method,
x%5E2-8x-6x%2B48=-1
x%5E2-14x-49=0
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-%28-14%29+%2B-+sqrt%28+%28-14%29%5E2-4%2A1%2A%28-49%29+%29%29%2F%282%2A1%29+
x+=+%2814+%2B-+sqrt%28+196%2B196%29%29%2F2+
Take it from there to solve for x
