expand (a+b)x^3-xy^2(a+b)

expand

(a + b) x^{3} - x y^{2} (a + b)

a x^{3} + x^{3} b - a x y^{2} - b x y^{2}

Solution steps

(a + b) x^{3} - x y^{2} (a + b)

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

Expand

x^{3} (a + b) : a x^{3} + x^{3} b

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

Expand

- x y^{2} (a + b) : - a x y^{2} - b x y^{2}

= a x^{3} + x^{3} b - a x y^{2} - b x y^{2}

(2 x y)^{4}

- 3 \frac{1}{2} \div \frac{4}{9}

(x^{2} + 6 x - 15) - (4 x^{2} - 3 x - 5)

\frac{( 3.542 \cdot 1 0 ^{- 6} ) ^{9}}{( 5.05 \cdot 1 0 ^{4} ) ^{12}}

\frac{39}{64}
