Hi all

Would appreciate any help!

For eachn, let the roots of the quadratic equation $\displaystyle x^2 + (2n+1)x + n^2 = 0$ be $\displaystyle a[n]$ and $\displaystyle b[n]$

Find the value of $\displaystyle 1/(a[3] + 1)(b[3] + 1) + 1/(a[4] + 1)(b[4] + 1) + ... + 1/(a[15] + 1)(b[15] + 1)$

Junior high math can be a killer
