expand 16*(a+b)^2-4a-4b

expand

16 \cdot (a + b)^{2} - 4 a - 4 b

16 a^{2} + 32 ab + 16 b^{2} - 4 a - 4 b

Solution steps

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

Expand

(a + b)^{2} : a^{2} + 2 ab + b^{2}

= 16 (a^{2} + 2 ab + b^{2}) - 4 a - 4 b

Apply the distributive law:

m (a + b + c) = ma + mb + m c

16 (a^{2} + 2 ab + b^{2}) = 16 a^{2} + 16 \cdot 2 ab + 16 b^{2}

= 16 a^{2} + 16 \cdot 2 ab + 16 b^{2} - 4 a - 4 b

Multiply the numbers:

16 \cdot 2 = 32

= 16 a^{2} + 32 ab + 16 b^{2} - 4 a - 4 b

p^{2} (- 2)^{2} \cdot p \cdot (- 5)^{2}

4 x^{2} - 60 + 176

\frac{1}{5} \cdot x \cdot \frac{2}{7} \cdot x \cdot \frac{14}{6}

\frac{x ^{3} - 4 - x + 4 x ^{2}}{x ^{3} + 3 x - 4}

\frac{( 4 x ^{8} - 10 x ^{6} - 6 x ^{4} )}{( 2 x ^{3} )}
