Answer 1

Step-by-step explanation:

If the equation has equal roots , then it's determinant is zero.

D = 0

b^2 - 4ac = 0

(coefficient of x)^2 - 4 (coefficient of x^2) constant = 0

[2(m-12)]^2 - 4(m-12)2 =0

4(m-12)^2 - 8(m-12) = 0

4(m^2 - 24m + 144) - 8m + 96 =0

4m^2 - 96m + 576 -8m + 96 =0

4m^2 - 104m + 672 = 0

m^2 - 26m + 144=0. (diving by 4 on both sides)

Now further solve the equation and find the answer.
