expand (10b-4/3 y)^2

expand

(10 b - \frac{4}{3} y)^{2}

\frac{900 b ^{2} - 240 b y + 16 y ^{2}}{9}

Solution steps

(10 b - \frac{4}{3} y)^{2}

Apply Perfect Square Formula:

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

(10 b - \frac{4}{3} y)^{2} = (10 b)^{2} - 2 \cdot 10 b \frac{4}{3} y + (\frac{4}{3} y)^{2}

= (10 b)^{2} - 2 \cdot 10 b \frac{4}{3} y + (\frac{4}{3} y)^{2}

Simplify

(10 b)^{2} - 2 \cdot 10 b \frac{4}{3} y + (\frac{4}{3} y)^{2} : \frac{900 b ^{2} - 240 b y + 16 y ^{2}}{9}

= \frac{900 b ^{2} - 240 b y + 16 y ^{2}}{9}

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

5 (\frac{3}{7} u - \frac{3}{13} v^{2})^{2}

\frac{( 3 + 4 x ) ^{3}}{( 4 - 3 x ) ^{4}}

3 (2 - 2)
