You can put this solution on YOUR website!
Square Root Property? 3x%5E2%2B12x%2B1=18 ?
Since you posted the question twice, maybe another tutor can see the way to use "Square Root Property".

3x%5E2%2B12x-17=0
You could complete the square to solve, and you will eventually get to
x=%28-12%2B-+sqrt%2812%5E2-4%2A3%2A%28-17%29%29%29%2F%282%2A3%29

x=%28-12%2B-+sqrt%28144%2B204%29%29%2F%282%2A3%29

x=%28-12%2B-+sqrt%28348%29%29%2F%282%2A3%29

x=%28-12%2B-+sqrt%284%2A87%29%29%2F%282%2A3%29

x=%28-12%2B-+2%2Asqrt%2887%29%29%2F%282%2A3%29

highlight%28x=-2%2B-+sqrt%2887%29%2F3%29
