39 = 3 x 13 52 = 2^2 x 13 169 = 13^2 LCM is: 2^2 x 3 x 13^2 = 2028
2 x 2 x 13 x w
-x2 - 11x + 26= -x2 - 13x + 2x + 26= (2x - x2) + (26 - 13x)= x(2 - x) + 13(2 - x)= (2 - x)(x + 13)
x^2-15x+14=0 Delta = (-15)^2-4*1*14 = 169 = 13^2 so x=(15-13)/2=1 or x=(15+13)/2=14
x^2 + (x+1 )^2 =365 x^2 +x^2 + 2x +1 =365 2x^2 + 2x = 364 x^2 + x = 182 = (x- 13)(x + 14) x =13, so integers are 13 and 14, squares 169 and 196, which total 365.
