The answer is x = 3i and x = -3i. {Where i= √(-1)}
An expression in the form a2 - b2 can be factored into (a - b)(a + b), but you have a2 + b2 so this factors into (a - bi)(a + bi). Check by multiplying the binomials: a2 + abi - abi - (bi)2 the [abi]'s cancel, and i2 = -1, so you have a2 + abi - abi - -b2 which is a2 + b2, so it checks out. In this case, a is x and b is 3.

What does 0 squared equal?
It equals 0. Zero times zero equals zero.
How do you factor 2x squared plus 8x plus 20 equals 0?
It can not be factored because its discriminant is less than zero
Solve 7 plus p equals 7?
p is obviously zero because any number x plus 0 equals itself.
What is X squared plus 6x minus 55?
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.
How do you solve x squared minus two x plus one equals zero?
x2-2x+1 = 0 (x-1)(x-1) = 0 x = 1 and also x = 1
