Answer:Answer:

The answer is x^2 + x =420

Explanation:

It is given that

The product of two consecutive integers is 420

Le x be the first number, then

second number is the next consecutive number of x which is (x +1)

The product of these numbers can be written as

x (x + 1) which is equal to 420

x (x + 1) = 420

x^2 + x = 420

So the quadratic equation is

x^2 + x = 420
