Question 798200: Find two consecutive positive even integers such that the square of the second integer summed with the first integer is 40. Write an equation and solve algebraically. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let the positive even consecutive integers be x & x+2
(x+2)^2+x=40
x^2+4x+4+x=40
x^2+5x-36=0
x^2+9x-4x-36=0
x(x+9)-4(x+9)=0
(x+9)(x-4)=0
x= 4
4 & 6
