Question

Find two consecutive numbers whose product is 210.

Answer 1

The two numbers are 14 and 15.

Answer 2

Answer:

two consecutive numbers are 14 and -15

Step-by-step explanation:

let the number be x and x + 1.

x(x + 1) = 210

x^2 + x = 210

x^2 + x - 210 = 0

(x + 5) (x - 14) = 0

x = -15 and 14
