Solution

expand

(7 k + 2 m)^{2}

Solution

49 k^{2} + 28 km + 4 m^{2}

Solution steps

(7 k + 2 m)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

(7 k)^{2} + 2 \cdot 7 k \cdot 2 m + (2 m)^{2} : 49 k^{2} + 28 km + 4 m^{2}

= 49 k^{2} + 28 km + 4 m^{2}
