 Question 88438: 3square of 27 + square root of 8 - 2square root of 75 Click here to see answer by stanbon(57399)

 Question 88552: I think this particular problem cannot be solved by I need verfify I'm doing it correctly. First I remove the radical from the equation by squaring both sides = x - 1 = x^2 - 6x + 9. Next I need to make the equation equal to zero = 0 = x^2 - 7x + 10. Then I need to factor (x - 2)(x - 5). When I plug -2 back into check I end up with radical -3 = -5 and when I plug -5 I end up with radical -6 = -8. Therefore is it true this equation has no solution?
