Question

the product of two consecutive number is 420 can you tell the numbers ​

Answer 1

Answer:

let the numbers be a and (a + 1) (consecutive numbers)

Step-by-step explanation:

Let take the integer as ‘’a’’ and its consecutive is ‘’a + 1’’

a2 + a - 420 = 0

a2 -20a + 21a - 420 = 0

a (a - 20) + 21 (a - 20) = 0

(a -20) (a + 21) = 0

a = 20

Answer 2

Answer:

let 1st no. =x

let 2nd no.=x+1

A.T.Q

x(x+1)=420

x2+x - 420= 0

now you solve this equation then you get two no. if first x=any negative then you should not take it .if second x= postive then you choose it and put the 1st no. and 2nd no.
