Solution for 1/2(h+5)(h)-88=0 equation: 


h in (-oo:+oo)

(1/2)*h*(h+5)-88 = 0

1/2*h*(h+5)-88 = 0

1/2*h*(h+5)-88 = 0

1/2*h^2+5/2*h-88 = 0

1/2*h^2+5/2*h-88 = 0

1/2*h^2+5/2*h-88 = 0

DELTA = (5/2)^2-(-88*1/2*4)

DELTA = 729/4

DELTA > 0

h = ((729/4)^(1/2)-5/2)/(1/2*2) or h = (-(729/4)^(1/2)-5/2)/(1/2*2)

h = 11 or h = -16

(h+16)*(h-11) = 0

(h+16)*(h-11) = 0

( h+16 )

h+16 = 0 // - 16

h = -16

( h-11 )

h-11 = 0 // + 11

h = 11

h in { -16, 11 }
