expand 64(10k-10m+1)^2

expand

64 (10 k - 10 m + 1)^{2}

- 12800 km + 6400 m^{2} - 1280 m + 6400 k^{2} + 1280 k + 64

Solution steps

64 (10 k - 10 m + 1)^{2}

(10 k - 10 m + 1)^{2} = - 200 km + 100 m^{2} - 20 m + 100 k^{2} + 20 k + 1

= 64 (100 m^{2} - 200 km - 20 m + 100 k^{2} + 20 k + 1)

Distribute parentheses

= 64 (- 200 km) + 64 \cdot 100 m^{2} + 64 (- 20 m) + 64 \cdot 100 k^{2} + 64 \cdot 20 k + 64 \cdot 1

Apply minus-plus rules

+ (- a) = - a

= - 64 \cdot 200 km + 64 \cdot 100 m^{2} - 64 \cdot 20 m + 64 \cdot 100 k^{2} + 64 \cdot 20 k + 64 \cdot 1

Simplify

- 64 \cdot 200 km + 64 \cdot 100 m^{2} - 64 \cdot 20 m + 64 \cdot 100 k^{2} + 64 \cdot 20 k + 64 \cdot 1 : - 12800 km + 6400 m^{2} - 1280 m + 6400 k^{2} + 1280 k + 64

= - 12800 km + 6400 m^{2} - 1280 m + 6400 k^{2} + 1280 k + 64
