factor 8+27n^3

factor

8 + 27 n^{3}

(3 n + 2) (9 n^{2} - 6 n + 4)

Solution steps

8 + 27 n^{3}

Write in the standard form

= 27 n^{3} + 8

Apply exponent rules

= (3 n)^{3} + 2^{3}

Apply Sum of Cubes Formula:

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

(3 n)^{3} + 2^{3} = (3 n + 2) (3^{2} n^{2} - 2 \cdot 3 n + 2^{2})

= (3 n + 2) (3^{2} n^{2} - 2 \cdot 3 n + 2^{2})

Simplify

(3 n + 2) (3^{2} n^{2} - 2 \cdot 3 n + 2^{2}) : (3 n + 2) (9 n^{2} - 6 n + 4)

= (3 n + 2) (9 n^{2} - 6 n + 4)
