Question 156948
Solve for d:
{{{18d^2+30d+12 = 0}}} Factor.
{{{(3d+3)(6d+4) = 0}}} Apply the zero product rule: If a*b = 0, then either a = 0, or b = o, or both.
{{{3d+3 = 0}}} or {{{6d+4 = 0}}}
If {{{3d+3 = 0}}} then {{{3d = -3}}} and {{{d = -1}}}
If {{{6d+4 = 0}}} then {{{6d = -4}}} and {{{d = -2/3}}}
