simplify x^2*(-2)x

Solution

simplify

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

Solution

- 2 x^{3}

Solution steps

x^{2} (- 2) x

Apply rule:

a (- b) = - ab

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

= - x^{2} \cdot 2 x

Apply exponent rule:

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

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

= - x^{2 + 1} \cdot 2

Add the numbers:

2 + 1 = 3

= - x^{3} \cdot 2

= - 2 x^{3}
