16. For what values of m does the quadratic equation (5m−3)x2− 4mx+m+1=0 have only one root?
m=−3,m=1
Step 1 :Let's calculate the discriminant and set it equal to 0: D=b2−4ac=(−4m)2−4(5m−3)(m+1)
Step 2 :Setting the discriminant equal to 0: 16m2−(m+1)(20m−12)=0
Step 3 :Solving for m, we get two values: m=−3 and m=1
Step 4 :m=−3,m=1
