factor r^3+125

Solution

factor

r^{3} + 125

Solution

(r + 5) (r^{2} - 5 r + 25)

Solution steps

r^{3} + 125

Rewrite

125

as

5^{3}

= r^{3} + 5^{3}

Apply Sum of Cubes Formula:

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

r^{3} + 5^{3} = (r + 5) (r^{2} - 5 r + 5^{2})

= (r + 5) (r^{2} - 5 r + 5^{2})

5^{2} = 25

= (r + 5) (r^{2} - 5 r + 25)
