Question

If p2x2-q2=0 then x=

Answer 1

Answer:

$x=\pm \frac{q}{p}$

Step-by-step explanation:

Given: $p^{2} x^{2} -q^{2} =0$

Find: The value of x.

In the given equation shift $q^{2}$ to the right hand side and then divide by $p^{2}.$

$p^{2} x^{2} -q^{2} =0$

$\Rightarrow p^{2} x^{2} =q^{2}$

$\Rightarrow x^{2} =\frac{q^{2} }{p^{2} }$

Taking square root both sides, we get:

$\Rightarrow x=\pm \frac{q}{p}$
