Question

If p2x2 - q2 = 0 find x​

Answer 1

Answer:

x=q/p

Step-by-step explanation:

p^2x^2-q^2=0

p^2x^2=q^2

x^2=q^2/p^2

x=√q^2/p2

x=q/p

Answer 2

Answer:

x = -q/p or x = q/p

Step-by-step explanation:

p²x² - q² = 0

=> (px)² - (q)² = 0

Identity – a² - b² = (a+b)(a-b)

=> (px+q)(px-q) = 0

Now, either of the factors should be zero.

=> px+q = 0

=> px = -q

=> x = -q/p

=> px-q = 0

=> px = q

=> x = q/p
