## Abstract

top
This paper gives further results about the distribution in the arithmetic progressions (modulo a product of two primes) of reducible quadratic polynomials $\left(an+b\right)\left(cn+d\right)$ in short intervals $n\in \left[x,x+{x}^{\vartheta }\right]$, where now $\vartheta \in \left(0,1\right]$. Here we use the Dispersion Method instead of the Large Sieve to get results beyond the classical level $\vartheta$, reaching $3\vartheta /2$ (thus improving also the level of the previous paper, i.e. $3\vartheta -3/2$), but our new results are different in structure. Then, we make a graphical comparison of the two methods.
