यदि (p(x)=(x+2)(x-7)) है तो ग्राफ (x)-अक्ष से किन बिंदुओं पर मिलेगा?
If (p(x)=(x+2)(x-7)), at which points will the graph meet the (x)-axis?
Explanation opens after your attempt
Correct Answer
B. ((-2,0)) और ((7,0))((-2,0)) and ((7,0))
Concept
Setting the factors to zero gives (x=-2) and (x=7). Tip: convert each zero into the point ((x,0)).
Why this answer is correct
The correct answer is B. ((-2,0)) और ((7,0)) / ((-2,0)) and ((7,0)). Setting the factors to zero gives (x=-2) and (x=7). Tip: convert each zero into the point ((x,0)).
Exam Tip
कारक शून्य करने पर (x=-2) और (x=7) मिलते हैं। टिप: शून्यक को ((x,0)) बिंदु में बदलें।
