expand 7.4x^2(2x^2-8.4x)

expand

7.4 x^{2} (2 x^{2} - 8.4 x)

14.8 x^{4} - 62.16 x^{3}

Solution steps

7.4 x^{2} (2 x^{2} - 8.4 x)

Apply the distributive law:

a (b - c) = ab - a c

7.4 x^{2} (2 x^{2} - 8.4 x) = 7.4 x^{2} \cdot 2 x^{2} - 7.4 x^{2} \cdot 8.4 x

= 7.4 x^{2} \cdot 2 x^{2} - 7.4 x^{2} \cdot 8.4 x

Simplify

7.4 x^{2} \cdot 2 x^{2} - 7.4 x^{2} \cdot 8.4 x : 14.8 x^{4} - 62.16 x^{3}

= 14.8 x^{4} - 62.16 x^{3}

\frac{27}{99}

- 7 - (- 10)

\frac{7}{9} \div \frac{2}{12}

(- 7 + 8 i) (5 + 4 i)

4 z^{2} - 7 z - 2
