यदि (p(x)=x-2+2x-15) है, तो ग्राफ के (x)-अक्ष कटान कौन से हैं?
If (p(x)=x-2+2x-15), what are the (x)-axis intersections of the graph?
Explanation opens after your attempt
A. ((3,0)) और ((-5,0))((3,0)) and ((-5,0))
Concept
(x-2+2x-15=(x+5)(x-3)), so the zeroes are (-5) and (3). Tip: form points ((x,0)) from factors.
Why this answer is correct
The correct answer is A. ((3,0)) और ((-5,0)) / ((3,0)) and ((-5,0)). (x-2+2x-15=(x+5)(x-3)), so the zeroes are (-5) and (3). Tip: form points ((x,0)) from factors.
Exam Tip
(x-2+2x-15=(x+5)(x-3)), इसलिए शून्यक (-5) और (3) हैं। टिप: गुणनखंडों से बिंदु ((x,0)) बनाएं।
