expand (m-7)^2

Solution

expand

(m - 7)^{2}

Solution

m^{2} - 14 m + 49

Solution steps

(m - 7)^{2}

Apply Perfect Square Formula:

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

(m - 7)^{2} = m^{2} - 2 m \cdot 7 + 7^{2}

= m^{2} - 2 m \cdot 7 + 7^{2}

Simplify

m^{2} - 2 m \cdot 7 + 7^{2} : m^{2} - 14 m + 49

= m^{2} - 14 m + 49
