3x2 +19x-14=0
Using the quadratic formula which is as follows:
x = {- b + (b2 - 4ac)1/2}/2a
x = {- 19 + (192 - 4(3)(-14))1/2}/2*3
x = {- 19 + (361 + 168)1/2}/6
x = {- 19 + (529)1/2}/6
Therefore, answer is x = {- 19 - (529)1/2}/6 or
x = {- 19 + (529)1/2}/6

Thank you very much i am really trying hard to understand this stuff but, i just can't get it. Hanks for your help
X = (-19±√529)/6 = (-19±23)/6
x = -42/6 = -7
x = 4/6 = 2/3
The roots are -7 or 2/3. The equation can be factored as (x+7)(3x-2)=0, confirming that result.
