A \(3x^2-2x+8=0\)
B \(3x^2-2x+2=0\)
C \(4x^2-2x+8=0\)
D \(3x^2+2x+8=0\)
Explanation opens after your attempt
Correct Answer
A. \(3x^2-2x+8=0\)
Step 1
Concept
Multiply the whole equation by (4) to remove the denominators. This gives \(3x^2-2x+8=0\).
Step 2
Why this answer is correct
The correct answer is A. \(3x^2-2x+8=0\). Multiply the whole equation by (4) to remove the denominators. This gives \(3x^2-2x+8=0\).
Step 3
Exam Tip
हर हटाने के लिए पूरे समीकरण को (4) से गुणा करें। इससे \(3x^2-2x+8=0\) मिलता है।

समीकरण \(\frac{2}{5}x^2+\frac{1}{5}x-2=0\) का पूर्णांक गुणांकों वाला रूप कौन-सा है?
What is the form with integer coefficients for \(\frac{2}{5}x^2+\frac{1}{5}x-2=0\)?
#quadratic-equations
#fractional-coefficients
#medium
A \(2x^2+x-10=0\)
B \(2x^2+x-2=0\)
C \(5x^2+x-2=0\)
D \(2x^2+5x-10=0\)
Explanation opens after your attempt
Correct Answer
A. \(2x^2+x-10=0\)
Step 1
Concept
Multiply the whole equation by (5) to remove denominator (5). This gives \(2x^2+x-10=0\).
Step 2
Why this answer is correct
The correct answer is A. \(2x^2+x-10=0\). Multiply the whole equation by (5) to remove denominator (5). This gives \(2x^2+x-10=0\).
Step 3
Exam Tip
हर (5) हटाने के लिए पूरे समीकरण को (5) से गुणा करें। इससे \(2x^2+x-10=0\) मिलता है।

समीकरण \(\frac{1}{3}x^2-\frac{2}{3}x+1=0\) का पूर्णांक गुणांकों वाला रूप कौन-सा है?
What is the form with integer coefficients for \(\frac{1}{3}x^2-\frac{2}{3}x+1=0\)?
#quadratic-equations
#fractional-coefficients
#medium
A \(x^2-2x+3=0\)
B \(x^2+2x+3=0\)
C \(3x^2-2x+1=0\)
D \(x^2-2x+1=0\)
Explanation opens after your attempt
Correct Answer
A. \(x^2-2x+3=0\)
Step 1
Concept
Multiply the whole equation by (3) to remove the denominator (3). This gives \(x^2-2x+3=0\).
Step 2
Why this answer is correct
The correct answer is A. \(x^2-2x+3=0\). Multiply the whole equation by (3) to remove the denominator (3). This gives \(x^2-2x+3=0\).
Step 3
Exam Tip
हर (3) हटाने के लिए पूरे समीकरण को (3) से गुणा करें। इससे \(x^2-2x+3=0\) मिलता है।
