m=-3/4 m=-4/3 easier to figure out the roots using the quadratic formula. {-b+\-[sqrt(b2-4ac)]}/2a (I hope you are aware of it). Before going and manually solving the eqn, its better to check if b2-4ac is positive or not.(if -ve, equation has imaginary roots).

**math**

lets start with the equation 2n(n+4) - 28 = (n+2)^2 using formula (a+b)^2=a^2+2ab+b^2 2n^2+8n-28=n^2+4n+32 simplyfying, n2+4n=32 Solving for n, we get n=4 So the even consecutive numbers are 4,6,and 8..... checking... 2(4*8)-28=36
