expand (k-10)^3

Solution

expand

(k - 10)^{3}

Solution

k^{3} - 30 k^{2} + 300 k - 1000

Solution steps

(k - 10)^{3}

Apply Perfect Cube Formula:

(a - b)^{3} = a^{3} - 3 a^{2} b + 3 a b^{2} - b^{3}

(k - 10)^{3} = k^{3} - 3 k^{2} \cdot 10 + 3 k \cdot 1 0^{2} - 1 0^{3}

= k^{3} - 3 k^{2} \cdot 10 + 3 k \cdot 1 0^{2} - 1 0^{3}

Simplify

k^{3} - 3 k^{2} \cdot 10 + 3 k \cdot 1 0^{2} - 1 0^{3} : k^{3} - 30 k^{2} + 300 k - 1000

= k^{3} - 30 k^{2} + 300 k - 1000
