Answer:
20&22
Step-by-step explanation:
let the numbers be X and X+2.
By question, X×(X+2)=440
or, X^2+2X=440
or, X^2+2X-440=0
or, X^2+(22-20)X-440=0
or, X^2+22X-20X-440=0
or, X(X+22)-20(X+22)=0
or, (X+22)(X-20)=0
Either,X-20=0 Or, X+22=0
•°•X=20(true) •°• X=-22(false)
•°•X=20
•°•X+2=20+2=22
•°• The two consecutive even numbers are 20 and 22.
