Question 1/2
Easy Mathematics
Quadratic Equations Introduction to Quadratic Equations Class 10 Level 29
((2x+1)(x-4)=0) का विस्तृत रूप क्या है?
What is the expanded form of ((2x+1)(x-4)=0)?
Explanation opens after your attempt
Correct Answer
A. \(2x^2-7x-4=0\)
Step 1
Concept
Expanding gives \(2x^2-8x+x-4=0\). Combining like terms gives \(2x^2-7x-4=0\).
Step 2
Why this answer is correct
The correct answer is A. \(2x^2-7x-4=0\). Expanding gives \(2x^2-8x+x-4=0\). Combining like terms gives \(2x^2-7x-4=0\).
Step 3
Exam Tip
विस्तार करने पर \(2x^2-8x+x-4=0\) मिलता है। समान पद जोड़कर \(2x^2-7x-4=0\) बनता है।

Question 2/2
Easy Mathematics
Quadratic Equations Introduction to Quadratic Equations Class 10 Level 28
((x+2)(x+3)=0) का विस्तृत रूप क्या है?
What is the expanded form of ((x+2)(x+3)=0)?
Explanation opens after your attempt
Correct Answer
A. \(x^2+5x+6=0\)
Step 1
Concept
Expansion gives \(x^2+3x+2x+6=0\). Combining like terms gives \(x^2+5x+6=0\).
Step 2
Why this answer is correct
The correct answer is A. \(x^2+5x+6=0\). Expansion gives \(x^2+3x+2x+6=0\). Combining like terms gives \(x^2+5x+6=0\).
Step 3
Exam Tip
विस्तार से \(x^2+3x+2x+6=0\) मिलता है। समान पद जोड़कर \(x^2+5x+6=0\) बनता है।
