factor X^3+8

Solution

factor

X^{3} + 8

Solution

(X + 2) (X^{2} - 2 X + 4)

Solution steps

X^{3} + 8

Rewrite

8

as

2^{3}

= X^{3} + 2^{3}

Apply Sum of Cubes Formula:

x^{3} + y^{3} = (x + y) (x^{2} - x y + y^{2})

X^{3} + 2^{3} = (X + 2) (X^{2} - 2 X + 2^{2})

= (X + 2) (X^{2} - 2 X + 2^{2})

2^{2} = 4

= (X + 2) (X^{2} - 2 X + 4)
