"First number squared equals the first number". This must be 1, but "they do not equal zero or one". No solution possible.
x = 5 / 6squared + 7
It can be solved by using the quadratic equation formula.
It cannot be solved because the discriminant of the quadratic equation is less than zero
It is, as stated, 2x2 + x - 1 = 0. That is the quadratic form.
It has no solutions because the discriminant is less than zero.
X=1
0 squared is 0. Zero times zero equals zero.
It equals 0. Zero times zero equals zero.
It can not be factored because its discriminant is less than zero

It is, as stated, 2x2 + x - 1 = 0. That is the quadratic form.
It is, as stated, x2 - 5x + 25/4 = 0
9x^2 + 2^2 = 0 3x +2 = 0 therefore: x=-2/3
