expand (10-x)^3

Solution

expand

(10 - x)^{3}

Solution

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

Solution steps

(10 - x)^{3}

Apply Perfect Cube Formula:

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

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

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

Simplify

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

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