यदि (p(x)=\frac{2}{5}x-6), तो किस मान पर (p(x)=0) होगा?
If (p(x)=\frac{2}{5}x-6), for which value will (p(x)=0)?
Explanation opens after your attempt
C. (x=15)
Concept
From \(\frac{2}{5}x-6=0\), \(\frac{2}{5}x=6\) and (x=15). With a fractional coefficient, multiply by the reciprocal.
Why this answer is correct
The correct answer is C. (x=15). From \(\frac{2}{5}x-6=0\), \(\frac{2}{5}x=6\) and (x=15). With a fractional coefficient, multiply by the reciprocal.
Exam Tip
\(\frac{2}{5}x-6=0\) से \(\frac{2}{5}x=6\) और (x=15) मिलता है। भिन्न गुणांक में उलटा गुणा करें।
