consecutive even means x and x+2 since they are 2 apart
sum of squares is 340 x^2+(x+2)^2=340 expand and add x^2+x^2+4x+4=340 2x^2+4x+4=340 divide both sides by 2 to make it easier x^2+2x+2=170 minus 170 bot sides x^2+2x-168=0 facotr (x-12)(x+14)=0 set each to zero x-12=0 add 12 x=12
x+14=0 minus 14 x=-14 but they has to e positive to disregard
