factor u^3+64

Solution

factor

u^{3} + 64

Solution

(u + 4) (u^{2} - 4 u + 16)

Solution steps

u^{3} + 64

Rewrite

64

as

4^{3}

= u^{3} + 4^{3}

Apply Sum of Cubes Formula:

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

u^{3} + 4^{3} = (u + 4) (u^{2} - 4 u + 4^{2})

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

4^{2} = 16

= (u + 4) (u^{2} - 4 u + 16)
