3x^2+14-5=0 I know the answer is 1/3, -5. But I have tryed and cannot get that. pleases show me the steps. i must be missing thank you so much

{(-14) + √[(14

^{2})-(4)(3)(-5)]}/(2*3)= 2/6 = 1/31. square 14 = 196

2. multiply 4, 3, and -5 to get -60

3. subtract -60 from 196 = 196--60= 196+60= 256

4. take the square root of 256 = √256= 16

2. multiply 4, 3, and -5 to get -60

3. subtract -60 from 196 = 196--60= 196+60= 256

4. take the square root of 256 = √256= 16

5. add 16 to -14 = 16 - 14=2

6. multiply 2 by 3 = 2*3 = 6

7. Divide 2 by 6 = 2/6 = 1/3

6. multiply 2 by 3 = 2*3 = 6

7. Divide 2 by 6 = 2/6 = 1/3

AND

{(-14) - √[(14

^{2})-(4)(3)(-5)]}/(2*3)= -30/6 = -51. square 14 = 196

2. multiply 4, 3, and -5 to get -60

3. subtract -60 from 196 = 196--60= 196+60= 256

4. take the square root of 256 = √256= 16

5. subtract 16 from -14 = -14 -16=-30

6. multiply 2 by 3 = 2*3 = 6

7. Divide -30 by 6 = -30/6 = -5

2. multiply 4, 3, and -5 to get -60

3. subtract -60 from 196 = 196--60= 196+60= 256

4. take the square root of 256 = √256= 16

5. subtract 16 from -14 = -14 -16=-30

6. multiply 2 by 3 = 2*3 = 6

7. Divide -30 by 6 = -30/6 = -5
