expand (2-7m^6)^2

Solution

expand

(2 - 7 m^{6})^{2}

Solution

4 - 28 m^{6} + 49 m^{12}

Solution steps

(2 - 7 m^{6})^{2}

Apply Perfect Square Formula:

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

(2 - 7 m^{6})^{2} = 2^{2} - 2 \cdot 2 \cdot 7 m^{6} + (7 m^{6})^{2}

= 2^{2} - 2 \cdot 2 \cdot 7 m^{6} + (7 m^{6})^{2}

Simplify

2^{2} - 2 \cdot 2 \cdot 7 m^{6} + (7 m^{6})^{2} : 4 - 28 m^{6} + 49 m^{12}

= 4 - 28 m^{6} + 49 m^{12}
