X=1
It is, as stated, x2 - 5x + 25/4 = 0
In such cases, there is usually a discontinuity when the denominator is zero. In other words, solve for:x + 2 = 0
Equals divided by non-zero equals are equal.
you have to first find the derivative of the original function. You then make the derivative equal to zero and solve for x.
X=1
It can be solved by using the quadratic equation formula.
Factor it. (x - 8)(x - 2) x = 2, 8
Without knowing what "x" is, we cannot say what the answer will be. And without knowing the answer, we cannot solve for "x". Set x at zero, for example. Zero squared is zero, plus 6 time zero which is zero, minus 55. Your answer is then -55. Set x at one, for example. One squared is one, plus 6 times 1 which is six, minus 55. Your answer is then -48. Etc.
x2-2x+1 = 0 (x-1)(x-1) = 0 x = 1 and also x = 1
It can't be solved because the discriminant of this quadratic equation is less than zero
Zero minus zero equals zero.
x = 5 / 6squared + 7
0 squared is 0. Zero times zero equals zero.
3x^2 + 5x - 8 = 0 + 8 + 8 3x^2 + 5x = 0 8x ^2 = 0
It Equals 2
zero
