Question

The product of two consecutive interes is 90 find the integers

Answer 1

Step-by-step explanation:

let the two consecutive integers are : x and (x +1)

product of two consecutive integers is 90

x(x+1) = 90

x^2+1x=90

x^2+1x-90

x^2+10x-9x-90

x(x+10)-9(x+10)

(x+10)(x-9)

x= -10 and x= 9

we do not consider -10

so x= 9

and x+1= 9+1 =10

therefore the two integers are 9 and 10
