expand 4a^2-2(2b)^3+ab(a=-1,b=2)

expand

4 a^{2} - 2 (2 b)^{3} + ab (a = - 1, b = 2)

4 a^{2} - 16 b^{3} + a^{2} b = 2

Solution steps

4 a^{2} - 2 (2 b)^{3} + ab (a = - 1, b = 2)

= 4 a^{2} - 2 (2 b)^{3} + ab (= a - 1 \cdot 2, = b)

Expand

ab (a = - 1, b = 2) : a^{2} b = 2

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

Expand

4 a^{2} - 2 (2 b)^{3} + a^{2} b : 4 a^{2} - 16 b^{3} + a^{2} b

4 a^{2} - 16 b^{3} + a^{2} b = 2

\frac{( 2 a + 1 ) ^{2}}{4}

a^{(2 n + 1) (2 n - 1)}

\frac{1}{2 ( 2 x + 6 )}

4 π (r + 5)^{3}
