expand (4l-2m)^3

expand

(4 l - 2 m)^{3}

64 l^{3} - 96 m l^{2} + 48 l m^{2} - 8 m^{3}

Solution steps

(4 l - 2 m)^{3}

Apply Perfect Cube Formula:

(a - b)^{3} = a^{3} - 3 a^{2} b + 3 a b^{2} - b^{3}

(4 l - 2 m)^{3} = (4 l)^{3} - 3 (4 l)^{2} \cdot 2 m + 3 \cdot 4 l (2 m)^{2} - (2 m)^{3}

= (4 l)^{3} - 3 (4 l)^{2} \cdot 2 m + 3 \cdot 4 l (2 m)^{2} - (2 m)^{3}

Simplify

(4 l)^{3} - 3 (4 l)^{2} \cdot 2 m + 3 \cdot 4 l (2 m)^{2} - (2 m)^{3} : 64 l^{3} - 96 m l^{2} + 48 l m^{2} - 8 m^{3}

= 64 l^{3} - 96 m l^{2} + 48 l m^{2} - 8 m^{3}

\frac{( d ^{\frac{1}{2}} \cdot e ^{x} )}{( d \cdot x ^{\frac{1}{2}} )}

4 x - 24

\frac{( 3 x ^{2} + 5 x + 2 )}{x + 1}

(2 x - 3)^{3} + (- 64)

(a) 7 + 357 - 35
