Question 1/2
Easy Mathematics
Quadratic Equations Introduction to Quadratic Equations Class 10 Level 29
कौन सा समीकरण (t) में द्विघात है?
Which equation is quadratic in (t)?
Explanation opens after your attempt
Correct Answer
A. \(t^2+3t+2=0\)
Step 1
Concept
In option (A), the variable (t) has highest power (2). So it is quadratic in (t).
Step 2
Why this answer is correct
The correct answer is A. \(t^2+3t+2=0\). In option (A), the variable (t) has highest power (2). So it is quadratic in (t).
Step 3
Exam Tip
विकल्प (A) में चर (t) की सबसे बड़ी घात (2) है। इसलिए यह (t) में द्विघात है।

Question 2/2
Easy Mathematics
Quadratic Equations Introduction to Quadratic Equations Class 10 Level 28
कौन सा समीकरण (x) में द्विघात है लेकिन (y) में नहीं?
Which equation is quadratic in (x) but not in (y)?
Explanation opens after your attempt
Correct Answer
A. \(x^2+5x+6=0\)
Step 1
Concept
In option (A), the variable (x) has degree (2). So it is quadratic in (x).
Step 2
Why this answer is correct
The correct answer is A. \(x^2+5x+6=0\). In option (A), the variable (x) has degree (2). So it is quadratic in (x).
Step 3
Exam Tip
विकल्प (A) में चर (x) की घात (2) है। इसलिए यह (x) में द्विघात है।
