It is very simple to make “Xoi Gac” – the unique red sky rice if you follow these steps. First, rinse and then soak the sky rice in water. After 6 to 8 hours, drain the rice well. Next, add the white wine to the “gac” seeds before you squish and squeeze them tightly. Then, mix the sky rice, the “gac” seeds and some salt together thoroughly and wait for 10 minutes. The next step is to steam the mixture for at least 30 minutes. Remember to check if it is fully cooked before gently mixing in the sugar and coconut milk. After steaming it for 5 more minutes, you now can serve this delicious dish with some shredded coconut.

\(\frac{\left(x-2\right)^2}{12}-\frac{\left(x+1\right)^2}{21}=\frac{\left(x-4\right)\left(x-6\right)}{28}\)

\(\Leftrightarrow\frac{7\left(x-2\right)^2}{84}-\frac{4\left(x+1\right)^2}{84}=\frac{3\left(x-4\right)\left(x-6\right)}{84}\)

\(\Leftrightarrow7\left(x-2\right)^2-4\left(x+1\right)^2=3\left(x-4\right)\left(x-6\right)\)

\(\Leftrightarrow7\left(x^2-4x+4\right)-4\left(x^2+2x+1\right)=3\left(x^2-10x+24\right)\)

\(\Leftrightarrow7x^2-28x+28-4x^2-8x-4=3x^2-30x+72\)

\(\Leftrightarrow7x^2-4x^2-3x^2-28x-8x+30+28-4-72=0\)

\(\Leftrightarrow-6x-48=0\)

\(\Leftrightarrow-6x=48\)

\(\Leftrightarrow x=-8\)

Vậy tập nghiệm của PT là : \(S=\left\{-8\right\}\)

Chúc bạn học tốt !!!
