Question 131295
{{{15t^2-11t=12}}} Start with the given equation


{{{15t^2-11t-12=0}}} Subtract 12 from both sides


{{{(3t-4)(5t+3)=0}}} Factor the left side



{{{3t-4=0}}} or {{{5t+3=0}}} Set each factor equal to zero



{{{t=4/3}}} or {{{t=-3/5}}} Solve for t in each case




---------------------------------

Answer:


So the solutions are 



{{{t=4/3}}} or {{{t=-3/5}}}

So our answer is C
