यदि \(x^2-8x+15=0\) के मूल \(\alpha\) और \(\beta\) हैं, तो (\(\alpha-1\)\(\beta-1\)) का मान क्या है?

If \(\alpha\) and \(\beta\) are roots of \(x^2-8x+15=0\), what is (\(\alpha-1\)\(\beta-1\))?

Explanation opens after your attempt
Correct Answer

A. (8)

Step 1

Concept

(\(\alpha-1\)\(\beta-1\)=\alpha\beta-\(\alpha+\beta\)+1). Here (15-8+1=8).

Step 2

Why this answer is correct

The correct answer is A. (8). (\(\alpha-1\)\(\beta-1\)=\alpha\beta-\(\alpha+\beta\)+1). Here (15-8+1=8).

Step 3

Exam Tip

(\(\alpha-1\)\(\beta-1\)=\alpha\beta-\(\alpha+\beta\)+1) होता है। यहाँ (15-8+1=8)।
