\(8x^2-30x+27=0\) और \(12x^2-31x+20=0\) में कौनसा मूल समान है?

Which root is common to \(8x^2-30x+27=0\) and \(12x^2-31x+20=0\)?

Explanation opens after your attempt
Correct Answer

A. \(x=\frac{3}{2}\)

Step 1

Concept

The first equation has roots \(\frac{3}{2},\frac{9}{4}\), and the second has roots \(\frac{3}{2},\frac{10}{9}\). In exams, solve both equations separately for the common root.

Step 2

Why this answer is correct

The correct answer is A. \(x=\frac{3}{2}\). The first equation has roots \(\frac{3}{2},\frac{9}{4}\), and the second has roots \(\frac{3}{2},\frac{10}{9}\). In exams, solve both equations separately for the common root.

Step 3

Exam Tip

पहले समीकरण के मूल \(\frac{3}{2},\frac{9}{4}\) और दूसरे के मूल \(\frac{3}{2},\frac{10}{9}\) हैं। परीक्षा में समान मूल के लिए दोनों समीकरण अलग हल करें।

Step 2

Why this answer is correct

The correct answer is A. \(x=\frac{7}{2},-\frac{1}{2}\). ((2x+1)(2x-7)=0), so \(x=-\frac{1}{2}\) and \(\frac{7}{2}\). In exams, change signs while writing roots.

Step 3

Exam Tip

((2x+1)(2x-7)=0), इसलिए \(x=-\frac{1}{2}\) और \(\frac{7}{2}\) हैं। परीक्षा में संकेत बदलकर मूल लिखें।
