xax=2\times 4
Variable a cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by ax.
x^{2}a=2\times 4
Multiply x and x to get x^{2}.
x^{2}a=8
Multiply 2 and 4 to get 8.
\frac{x^{2}a}{x^{2}}=\frac{8}{x^{2}}
Divide both sides by x^{2}.
a=\frac{8}{x^{2}}
Dividing by x^{2} undoes the multiplication by x^{2}.
a=\frac{8}{x^{2}}\text{, }a\neq 0
Variable a cannot be equal to 0.
