Question

1 Attempt any two of the following.
Find m if (m - 12) x + 2 (m-12) + 2 = 0 has real and equal roots​

Answer 1

Step-by-step explanation:

mx-12x+2m-24+2=0

mx-12x+2m-22=0

X(m-12)+2m-22=0

°.° a=m-12 , b=2m , c=-22

It is given that it has real roots,

So D=0

Now, D=b2-4ac

0 = 4m*2 - 4×(m-12)(-22)

0 = 4m2 + 88m - 1056

0 = m2 + 22m - 264

After further middle term splitting, you will got the right answer...
