किसी संख्या का वर्ग उस संख्या के (5) गुने से (6) अधिक है। यदि संख्या (x) है तो समीकरण क्या होगा?
The square of a number is (6) more than (5) times the number. If the number is (x), what is the equation?
#quadratic equations
#word problem
#forming equation
A \(x^2=5x+6\)
B \(x^2+5x=6\)
C \(5x^2=x+6\)
D \(x^2=6x+5\)
Explanation opens after your attempt
Correct Answer
A. \(x^2=5x+6\)
Step 1
Concept
The square is \(x^2\), and (6) more than (5) times the number is (5x+6). So the equation is \(x^2=5x+6\).
Step 2
Why this answer is correct
The correct answer is A. \(x^2=5x+6\). The square is \(x^2\), and (6) more than (5) times the number is (5x+6). So the equation is \(x^2=5x+6\).
Step 3
Exam Tip
संख्या का वर्ग \(x^2\) और (5) गुने से (6) अधिक (5x+6) है। इसलिए समीकरण \(x^2=5x+6\) बनेगा।

Quadratic Equations Introduction to Quadratic Equations Class 10 Level 29
यदि (a=2), (b=0), (c=-18) हैं तो समीकरण क्या होगा?
If (a=2), (b=0), (c=-18), what is the equation?
#quadratic equations
#forming equation
#standard form
A \(2x^2-18=0\)
B \(2x^2+18=0\)
C \(2x^2+18x=0\)
D \(18x^2-2=0\)
Explanation opens after your attempt
Correct Answer
A. \(2x^2-18=0\)
Step 1
Concept
Substituting in standard form gives \(2x^2+0x-18=0\). This is written as \(2x^2-18=0\).
Step 2
Why this answer is correct
The correct answer is A. \(2x^2-18=0\). Substituting in standard form gives \(2x^2+0x-18=0\). This is written as \(2x^2-18=0\).
Step 3
Exam Tip
मानक रूप में रखने पर \(2x^2+0x-18=0\) मिलता है। इसे \(2x^2-18=0\) लिखते हैं।

Quadratic Equations Introduction to Quadratic Equations Class 10 Level 29
कौन सा रूप (a=3), (b=-4), (c=-2) को दर्शाता है?
Which form represents (a=3), (b=-4), (c=-2)?
#quadratic equations
#forming equation
#coefficients
A \(3x^2-4x-2=0\)
B \(3x^2+4x-2=0\)
C \(3x^2-2x-4=0\)
D \(4x^2-3x-2=0\)
Explanation opens after your attempt
Correct Answer
A. \(3x^2-4x-2=0\)
Step 1
Concept
Putting the values in \(ax^2+bx+c=0\) gives \(3x^2-4x-2=0\). Watch the sign of (b).
Step 2
Why this answer is correct
The correct answer is A. \(3x^2-4x-2=0\). Putting the values in \(ax^2+bx+c=0\) gives \(3x^2-4x-2=0\). Watch the sign of (b).
Step 3
Exam Tip
मानक रूप \(ax^2+bx+c=0\) में मान रखने पर \(3x^2-4x-2=0\) मिलता है। (b) का चिन्ह ध्यान रखें।
