If (x^2 \neq 4), what is the simplified form of (\dfrac{x^4-16}{x^2-4})?यदि (x^2 \neq 4), तो (\dfrac{x^4-16}{x^2-4}) का सरल रूप क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (,x^2+4,)(,x^2+4,)
(x^4-16=(x^2-4)(x^2+4)), so the simplified form is (x^2+4). In exams, treat (x^4) as ((x^2)^2) for factorisation.(x^4-16=(x^2-4)(x^2+4)), इसलिए सरल रूप (x^2+4) है। परीक्षा में (x^4) को ((x^2)^2) समझकर factor करें।
