Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23
यदि (p(x)=x-2-2(b-4)x+(b-4)2) है, तो ग्राफ (x)-अक्ष को किस (x)-मान पर स्पर्श करेगा?
If (p(x)=x-2-2(b-4)x+(b-4)2), at which (x)-value will the graph touch the (x)-axis?
Explanation opens after your attempt
Correct Answer
A. (x=b-4)
Step 1
Concept
It is ((x-(b-4))2), so the repeated zero is (b-4). Tip: a perfect square form shows the zero quickly.
Step 2
Why this answer is correct
The correct answer is A. (x=b-4). It is ((x-(b-4))2), so the repeated zero is (b-4). Tip: a perfect square form shows the zero quickly.
Step 3
Exam Tip
यह ((x-(b-4))2) है इसलिए दोहराया शून्यक (b-4) है। टिप: पूर्ण वर्ग रूप में शून्यक तुरंत दिखता है।
