Question 234414
{{{x^2 + 8x = 3}}}

{{{x^2 + 8x -3 = 0}}}

the quadratic eauation is as follows, with a=1, b=8 and c=-3

{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}

{{{x = (-8 +- sqrt( 8^2-4*1*-3 ))/(2*-3) }}}

{{{x = (-8 +- sqrt(64-(-12)))/-6}}}

{{{x = (-8 +- sqrt(80))/-6}}}

{{{x = (-8 +- sqrt(16*5))/-6}}}

{{{x = (-8 +- 4sqrt(5))/-6}}}

{{{x = (-4 +- 2sqrt(5))/-3}}}
