If (p(x)=8x+3) and (q(x)=3x+2), what is (p(x)-q(x))?यदि (p(x)=8x+3) और (q(x)=3x+2), तो (p(x)-q(x)) क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(5x+1\)\(5x+1\)
\(p(x)-q(x)=(8x+3)-(3x+2)\). Removing the brackets gives \(8x+3-3x-2\), so \((8x-3x)+(3-2)=5x+1\). Therefore, the correct answer is \(5x+1\). \(11x+5\) would be obtained by adding the two polynomials, not subtracting them. Exam tip: while subtracting polynomials, change the sign of every term in the second polynomial.\(p(x)-q(x)=(8x+3)-(3x+2)\) है। कोष्ठक हटाने पर \(8x+3-3x-2\) मिलता है, अर्थात \((8x-3x)+(3-2)=5x+1\)। इसलिए सही उत्तर \(5x+1\) है। \(11x+5\) जोड़ करने पर मिलता है, घटाने पर नहीं। परीक्षा टिप: बहुपद घटाते समय दूसरे बहुपद के प्रत्येक पद का चिन्ह बदलना न भूलें।
