Answer 1

$\huge \boxed{\mathfrak{Question} \downarrow}$

• Simplify ⇨ $\frac { 1 } { 3 } ( \frac { - 9 } { 10 } ) ( - x ) ( - x )$

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\frac { 1 } { 3 } ( \frac { - 9 } { 10 } ) ( - x ) ( - x )$

Multiply -x and -x to get $\left(-x\right)^{2}$.

$\frac{1}{3}\times \left(\frac{-9}{10}\right)\left(-x\right)^{2}$

Multiply $\frac{1}{3}$ by $-\frac{9}{10}$ by multiplying the numerator by the numerator and the denominator by the denominator.

$\frac{1\left(-9\right)}{3\times 10}\left(-x\right)^{2}$

Carry out the multiplications in the fraction $\frac{1\left(-9\right)}{3\times 10}$.

$\frac{-9}{30}\left(-x\right)^{2}$

Reduce the fraction$\frac{-9}{30}$ to its lowest terms by extracting and cancelling out 3.

$-\frac{3}{10}\left(-x\right)^{2}$

Calculate -x to the power of 2 and get x².

$\huge\boxed{ \boxed{ \bf \: -\frac{3}{10}x^{2} }}$
