Question

The product of two consecutive even integers is 120.

How do I write an algebraic expression for each even number and write an algebraic equation for this problem?

Answer 1

let n be the first integer. what is the second integer if they are consecutive even integers (in terms of n)

Answer 2

well: x(x + 2)

Answer 3

good
and what does that equal to?

Answer 4

x^2 + 2x

Answer 5

and according to the problem, what numerical value is that equal to?

Answer 6

one of the integers that equal to 120?

Answer 7

well, what i meant was x^2 + 2x = 120
an equation you can solve

Answer 8

Oh :P yea, so the answer to those two questions is:
Algebraic expression: x(x + 2) and x(x + 2)
Algebraic equation: x^2 + 2x = 120
?

Answer 9

expression for each even number: n and (n+2)
equation: n(n+2)= 120 or n^2+2n-120=0

Answer 10

THanks guys!
