expand (-8k)^2-4(12)(k^2)

expand

(- 8 k)^{2} - 4 (12) (k^{2})

16 k^{2}

Solution steps

(- 8 k)^{2} - 4 (12) (k^{2})

Remove parentheses:

(a) = a

= (- 8 k)^{2} - 4 \cdot 12 k^{2}

(- 8 k)^{2} = 8^{2} k^{2}

4 \cdot 12 k^{2} = 48 k^{2}

= 8^{2} k^{2} - 48 k^{2}

8^{2} = 64

= 64 k^{2} - 48 k^{2}

Add similar elements:

64 k^{2} - 48 k^{2} = 16 k^{2}

= 16 k^{2}

\frac{( - 12 - 2 x ) ( 70 x + 420 )}{x}

\frac{h - 2}{2 ( 1 + 2 h )}

y (x y + y) (x - 1) y^{'} (x)

(e^{x y} + e^{y})^{4}

\frac{1}{12} e^{4 x} (2 x - 1)
