Answer :
Answer:
-420
Step-by-step explanation:
Let x be the smaller of two consecutive integers. Then the larger of these two integers is x + 1.
The product of these two integers is
[tex]x(x+1)=x^2+x[/tex]
The product of two consecutive integers is 420, so
[tex]x^2+x=420\\ \\x^2+x-420=0[/tex]
The constant of the quadratice equation is -420.
