Question

The product of two consecutive integers is 420. Which quadratic equation can be used to find x, the lesser number? x2 + 1 = 420 x2 + 2 = 420 x2 + x = 420 x2 + 2x = 420

Answer 1

Explanation:

Its CCCCCCCCCCCCCCC

Answer 2

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
