Rearrange: x2 - 10x + 25 = 0ie (x - 5)(x - 5) = 0x = 5Check: x2 = 25; 10x - 25 = 50 - 25 = 25. Job done
No solution in integers, quadratic formula gives roots as 6.73 & 3.27

The GCF is 10x.
(10x-3(10x+3)
x2 + 9x2 = 10x2
It can't be solved because the discriminant of this quadratic equation is less than zero
