Question 301465: Solve by factoring and using the principle of zero products. Show all work necessary.
2k2 = -30k - 100

2k^2=-30k-100
2k^2+30x+100=0
2(k^2-15k-50)=0
k=(15+-sqrt(-15^2-4*1*-50])/2*1
k=(15+-sqrt[225+200])/2
k=(15+-sqrt425)/2
k=(15+-20.62)/2
k=(15+20.62)/2
k=35.62/2
k=17.81 ans.
k=(15-20.62)/2
k=-5.62/2
k=-2.81 ans.
