यदि \(\sqrt{3}\) एक बहुपद \(x^2+kx+3\) का दोहरा शून्यक है, तो (k) क्या होगा?

If \(\sqrt{3}\) is a repeated zero of \(x^2+kx+3\), what is (k)?

Explanation opens after your attempt
Correct Answer

A. \(-2\sqrt{3}\)

Step 1

Concept

Both zeroes are \(\sqrt{3}\), so the sum is \(2\sqrt{3}\). In \(x^2+kx+3\), the sum is (-k), hence \(k=-2\sqrt{3}\).

Step 2

Why this answer is correct

The correct answer is A. \(-2\sqrt{3}\). Both zeroes are \(\sqrt{3}\), so the sum is \(2\sqrt{3}\). In \(x^2+kx+3\), the sum is (-k), hence \(k=-2\sqrt{3}\).

Step 3

Exam Tip

दोनों शून्यक \(\sqrt{3}\) हैं, इसलिए योग \(2\sqrt{3}\) है। \(x^2+kx+3\) में योग (-k) है, अतः \(k=-2\sqrt{3}\)।

यदि ग्राफ ((0,7)) से गुजरता है, तो क्या इससे (0) शून्यक सिद्ध होता है?

If a graph passes through ((0,7)), does it prove that (0) is a zero?

Explanation opens after your attempt
Correct Answer

A. नहीं, क्योंकि (y=7) हैNo, because (y=7)

Step 1

Concept

For a zero, (y=0) is needed. In ((0,7)), (y=7), so (0) is not a zero.

Step 2

Why this answer is correct

The correct answer is A. नहीं, क्योंकि (y=7) है / No, because (y=7). For a zero, (y=0) is needed. In ((0,7)), (y=7), so (0) is not a zero.

Step 2

Why this answer is correct

The correct answer is A. क्योंकि यह ((x-5)2+4) है / Because it is ((x-5)2+4). ((x-5)2+4) is always positive, so (p(x)=0) will not occur. Tip: adding a positive number to a square gives no real intersection.

Step 3

Exam Tip

((x-5)2+4) हमेशा धनात्मक है, इसलिए (p(x)=0) नहीं होगा। टिप: वर्ग में धनात्मक संख्या जुड़ने पर वास्तविक कटान नहीं मिलता।

यदि (p(x)=x-2+dx+d-2) और \(d\neq0\) है तो ग्राफ (x)-अक्ष को क्यों नहीं काटेगा?

If (p(x)=x-2+dx+d-2) and \(d\neq0\), why will the graph not cut the (x)-axis?

Correct Answer

A. क्योंकि इसका विविक्तकर ऋणात्मक हैBecause its discriminant is negative

Step 1

Concept

The discriminant is \(d^2-4d^2=-3d^2<0\), so there are no real zeroes. Tip: a negative discriminant means no (x)-axis intersection.

Step 2

Why this answer is correct

The correct answer is A. क्योंकि इसका विविक्तकर ऋणात्मक है / Because its discriminant is negative. The discriminant is \(d^2-4d^2=-3d^2<0\), so there are no real zeroes. Tip: a negative discriminant means no (x)-axis intersection.

Step 3

Exam Tip

विविक्तकर \(d^2-4d^2=-3d^2<0\) है इसलिए वास्तविक शून्यक नहीं हैं। टिप: ऋणात्मक विविक्तकर का अर्थ (x)-अक्ष कटान नहीं है।

यदि (p(x)=x-8+1) है तो उसके ग्राफ के वास्तविक शून्यकों की संख्या क्या है?

If (p(x)=x-8+1), what is the number of real zeroes of its graph?

Explanation opens after your attempt
Correct Answer

A. शून्यZero

Step 1

Concept

For real (x), \(x^8\geq0\), so \(x^8+1>0\). Tip: an always positive polynomial does not cut the (x)-axis.

Step 2

Why this answer is correct

The correct answer is A. शून्य / Zero. For real (x), \(x^8\geq0\), so \(x^8+1>0\). Tip: an always positive polynomial does not cut the (x)-axis.

Step 3

Exam Tip

वास्तविक (x) के लिए \(x^8\geq0\), इसलिए \(x^8+1>0\) है। टिप: हमेशा धनात्मक बहुपद (x)-अक्ष को नहीं काटता।
