x2 - 5x = 0x (x - 5) = 0x = 0andx = 5
x2 - 10x + 25 = 0(x - 5)(x - 5) = 0x - 5 = 0x = 5
There is no number that can multiplied by 0 to get 1. The equation 0x = 1 has no solution bcause 0x = 0 whatever number x may be. You might think that 1/0 times 0 would equal 1 but 1/0 is not a number.
x^2 + 12x + 36 = 0(x + 6)(x + 6) = 0(x + 6)^2 = 0√(x + 6)^2 = ± √0x + 6 = 0x + 6 - 6 = 0 - 6x = 6
