What is obtained after simplifying (-4(x+3))?(-4(x+3)) को सरल करने पर क्या मिलेगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(-4x-12\)\(-4x-12\)
Using the distributive property, multiply \(-4\) by each term inside the bracket: \(-4\times x=-4x\) and \(-4\times 3=-12\). Therefore, \(-4(x+3)=-4x-12\). In \(-4x+12\), the sign of the constant term is incorrect. Exam tip: When multiplying by a negative number, check the sign of every term carefully.वितरण गुणधर्म के अनुसार \(-4\) को कोष्ठक के प्रत्येक पद से गुणा करते हैं: \(-4\times x=-4x\) और \(-4\times 3=-12\)। इसलिए \(-4(x+3)=-4x-12\) होगा। \(-4x+12\) में स्थिर पद का चिह्न गलत है। परीक्षा टिप: ऋणात्मक संख्या से गुणा करते समय प्रत्येक पद के चिह्न पर विशेष ध्यान दें।
