If (p(x)=5x-12), what is (p(x)-p(-x))?

A. \(10x\)
Simple Explanation
दिया है \(p(x)=5x-12\)। \(x\) के स्थान पर \(-x\) रखने पर \(p(-x)=5(-x)-12=-5x-12\) मिलता है। अतः \(p(x)-p(-x)=(5x-12)-(-5x-12)=5x-12+5x+12=10x\)। इसलिए सही उत्तर \(10x\) है। \(0\) केवल तब मिलता जब दोनों व्यंजक समान होते। परीक्षा टिप: \(p(-x)\) निकालते समय \(x\) वाले प्रत्येक पद में \(x\) को \(-x\) से बदलें। / Given \(p(x)=5x-12\). Replacing \(x\) with \(-x\) gives \(p(-x)=5(-x)-12=-5x-12\). Therefore, \(p(x)-p(-x)=(5x-12)-(-5x-12)=5x-12+5x+12=10x\). Hence, \(10x\) is correct. \(0\) would result only if the two expressions were identical. Exam tip: while finding \(p(-x)\), substitute \(-x\) for every occurrence of \(x\).
