simplify 2x^2*(-3)x

Solution

simplify

2 x^{2} \cdot (- 3) x

- 6 x^{3}

Solution steps

2 x^{2} (- 3) x

Multiply the numbers:

2 (- 3) = - 6

= - 6 x^{2} x

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

x^{2} x = x^{2 + 1}

= - 6 x^{2 + 1}

Add the numbers:

2 + 1 = 3

= - 6 x^{3}

\frac{12}{121}

\frac{sin ^{4} ( 3 t )}{16 t ^{2}}

6 \div \frac{10}{7}

\frac{\frac{x}{x + 1} - \frac{1}{x}}{\frac{x}{x + 1} + \frac{1}{x}}

\frac{2 x ^{2} - x - 1}{x - 1}
