Given the points $A = [1;5]$ and $B = [-4;2]$, specify all the points $C$ lying on the $x$-axis, such that the area of the triangle $ABC$ is $14$. Hint: Use a cross product of vectors.
$C_1=[2;0];\ C_2=\left[-\frac{50}3;0\right]$
$C_1=[1;0];\ C_2=\left[-\frac{47}3;0\right]$
$C_1=[2;0];\ C_2=\left[-\frac{47}3;0\right]$
$C_1=[1;0];\ C_2=\left[-\frac{50}3;0\right]$
