Please solve question 10 ,11 ,12,13 ,14

Dear Student,
x2- 4x +(m-4) = 0
In an equation if  the determinant =0  then roots are equal
D= b2 - 4ac = 0
=> 42 -4 x 1 x (m-4) =0
=> 16 - 4m +16 = 0
=> -4m = -32
=> m = -32/-4
=> m = 8
 The solution to the question number 10 is given . For the next questions please give it in a separate thread. Looking forward to hear from you again.
Regards.
