# Solve the following quadratic equations using quadratic formula.

36x^{2} – 12ax + (a^{2} – b^{2}) = 0

Answer :

36x^{2} – 12ax + (a^{2} –b^{2}) = 0

⇒ a = 36, b = –12a and c = a^{2} – b^{2}

(–12a)^{2}– 4 (36)(a^{2} – b^{2})

= 144a^{2} – 144(a^{2} – b^{2})

= 144a^{2} – 144a^{2} + 144b^{2}

= 144 b^{2}
