What is the value of lim x→7 (x^2 - 49)/(x - 7)?
lim x→7 (x^2 - 49)/(x - 7) का मान क्या है?
Show answer and explanation
Correct Answer
A. 14
ExplanationStep 1: Factor the difference of squares. Step 2: x^2 - 49 = (x-7)(x+7); after cancellation, the limit is 7+7 = 14. Step 3: For 0/0 limits, factorization is often the fastest method.
Step 1: Difference of squares factor करें। Step 2: x^2 - 49 = (x-7)(x+7); cancel करने पर limit 7+7 = 14। Step 3: 0/0 form में factorization बहुत काम आता है।
