How do you factor x2 plus 4x - 8?

Answer 1

That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: -2 plus or minus 2 times the square root of 3

x = 1.4641
x = -5.4641

Answer 2

2(x3 - x - 4)

If that were 2x2, the answer would be 2(x - 2)(x + 1)

Answer 3

That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: 2 plus or minus the square root of 6.

x = 4.4494897427831779

x = -0.4494897427831779

Answer 4

Assuming the equation equates to 0.

X2 - 4 = 0

X2 = 4

X * X = 4

X = 2.

Answer 5

(x + 2)(x - 2)

Answer 6

(x^2 + 1)(x^2 - 2)
