The sum of consecutive even integers is 80

x+x2

x(x+2)=80

x^2+2x-80+0

x^2+10x-8x-80=0

x(x+10)-8(x+10)=0

(x+10)(x-8)=0

x=8 or -10

the numbers are 8 and 10 or -8 and -10

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
