Question

Which solution to the equation mc002-1.jpg is extraneous? g = –4 g = –4 and g = 16 neither g = –4 nor g = 16 g = 16

Answer 1

The equation here is   3/(2g+8) = (g+2)/ (g^2 – 16 )

Solution:

Simplified equation is 2g +4 = 3g -12 (equa ii)

Now putting values in equa ii

• G=-4 gives ans -4=-24

• G=-4 and 16, ans -4=36

• G=neither -4 nor 16

• G=16 , ans 36=36 (verified answer)
