x2 + 4 = 0
then get the x on one side.
x2 = -4
then find the square root of both which would cancel the square on the x.
therefore the answer is: x = the square root of -4 = i squared root 4, which is a complex number ( imaginary number) since you cannot find the square root of oa negative number

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
Factor it. (x - 8)(x - 2) x = 2, 8
It can't be solved because the discriminant of the given quadratic equation is less than zero meaning it has no real roots.
p is obviously zero because any number x plus 0 equals itself.
