The product of three and a squared number is twice the sum of the number and four

Mamont248 [21]

From the text of the task we can write the equation:

$3 x^{2} =2(x+4)\\
\\
3x^2=2x+8\\
\\
3x^2-2x-8=0\\
\\
\Delta=(-2)^2-4.3.(-8)=4+96=100\\
\\
x=\frac{2 \pm\sqrt{100}}{2.3}=\frac{2 \pm10}{6}\\
\\
x_1=\frac{2-10}{6}=-\frac{8}{6}=-\frac{4}{3}\\
\\
x_2=\frac{2+10}{2.3}=\frac{12}{6}=2$
