Question

This section contains 1 Assertion-Reason type question, which has 4 choices (A), (B), (C) and (D) out of which ONLY ONE is correct
.
A : The tangent at x = 1 to the curve y = x3x2x + 2 again meets the curve at x = –2.
R : When a equation of a tangent solved with the curve, repeated roots are obtained at point of tangency.

इस खण्ड में 1 कथन-कारण प्रकार का प्रश्न है, जिसमें 4 विकल्प (A), (B), (C) तथा (D) दिये गये हैं, जिनमें से केवल एक सही है।

A : x = 1 पर वक्र y = x3x2x + 2 की स्‍पर्श रेखा, वक्र से पुन: x = –2 पर मिलती है।
R : जब एक स्‍पर्श रेखा के समीकरण को वक्र के साथ हल किया जाता है, तब स्‍पर्शिता के बिंदु पर पुनरावर्त मूल पाये जाते हैं।
