Resumen

LetNbe the number of affine zeros of a pair of quadratic forms inn+1 variables defined over a finite fieldF_q. We give upper and lower bounds forNand show that these bounds are optimal. One result states that ifn+1≥10 and every quadratic form in the pencil has order at least three, then N-q^n-1<q^n-2.
