Question 696757
{{{4x^2+8x-p=0}}}

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


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


{{{x = (-8 +- sqrt(64+16p ))/8 }}}


{{{x = (-8 +- sqrt(16(4+p )))/8 }}}



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


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


{{{x = -1 +- (1/2)sqrt(4+p )}}}

solutioms:

{{{x = -1 +(1/2)sqrt(4+p )}}}

or

{{{x = -1 -(1/2)sqrt(4+p )}}}
