Solution

expand

(k - 3)^{2}

Solution

k^{2} - 6 k + 9

Solution steps

(k - 3)^{2}

Apply Perfect Square Formula:

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

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

= k^{2} - 2 k \cdot 3 + 3^{2}

Simplify

k^{2} - 2 k \cdot 3 + 3^{2} : k^{2} - 6 k + 9

= k^{2} - 6 k + 9
