Correct Answer

A. भुजाएं (x+3) और (x-5)correct signed sides

Step 1

Concept

Since (3+(-5)=-2) and (3\cdot(-5)=-15), the sides are (x+3) and (x-5). In exams check sum and product with signs.

Step 2

Why this answer is correct

The correct answer is A. भुजाएं (x+3) और (x-5) / correct signed sides. Since (3+(-5)=-2) and (3\cdot(-5)=-15), the sides are (x+3) and (x-5). In exams check sum and product with signs.

Step 3

Exam Tip

(3+(-5)=-2) और (3\cdot(-5)=-15) इसलिए भुजाएं (x+3) और (x-5) हैं। परीक्षा में चिन्ह सहित योग और गुणनफल जांचें।
