Question 695911
Apply quadratic formula
x = {{{(-(-12)+-sqrt(-12^2-4(3)(7)))/(2*3)}}}
...
x = {{{(12 +- sqrt(144-84))/6}}}
...
x = {{{(12 +- sqrt(60))/6}}}
...
x = {{{(12 +- 2sqrt(15))/6}}}
...
x = {{{2+-sqrt(15)/3}}}
...
Product of ({{{2+sqrt(15)/3)}}})({{{2-sqrt(15)/3}}})
{{{2(2) - 2sqrt(15)/3 + 2sqrt(15)/3 - (sqrt(15)/3)^2}}}
...
{{{4 - 15/9 = 4(9/9) - 15/9 = 36/9 - 15/9 = 21/9 = highlight_green(7/3)}}}
