expand 2(16x^4-72^2=81)

expand

2 (16 x^{4} - 7 2^{2} = 81)

32 x^{4} - 10368 = 81

Solution steps

2 (16 x^{4} - 7 2^{2} = 81)

= 2 (16 x^{4} - 7 2^{2} \cdot 81 =)

Apply the distributive law:

a (b - c) = ab - a c

a = 2, b = 16 x^{4}, c = 7 2^{2} = 81

2 \cdot 16 x^{4} - 2 \cdot 7 2^{2} = 81

2 \cdot 16 x^{4} - 7 2^{2} \cdot 2 = 81

Expand

2 \cdot 16 x^{4} - 7 2^{2} \cdot 2 : 32 x^{4} - 10368

32 x^{4} - 10368 = 81

\frac{z + 1}{z ( z - 1 )}

f (10 x^{4} - 18 x^{2} + 2 x + 3) d x

(y^{3}) (e^{t} + t e^{t})

\frac{2}{( x + 2 + 2 j ) ( x + 2 - 2 j ) ( x + 2 )}

(5 x + 4 y) (5 x - 4 y)
