$\left(\dfrac{2}{5}a^2x\right)\left(-\dfrac{1}{5}x^2a\right)=\left(\dfrac{2}{5}\right)\left(-\dfrac{1}{5}\right)(a^2xx^2a)=-\dfrac{2}{25}a^{2+1}x^{1+2}\\\\=\boxed{-\dfrac{2}{25}a^3x^3}$

Aleena expands 2xx+3-5(x-2) as 2x2+3-5x-10. Has she expanded it correctly? Please identify the mistakes and write the correct wa

Nimfa-mama [501]

The given expression is :

2xx+3-5(x-2)

We know that, $x{\cdot}x=x^2$

$=2x^2+3-5(x-2)\\\\=2x^2+3+(-5)(x)+(-5)(-2)\\\\=2x^2+3-5x+10$

Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
