Correct Answer

C. (9)correct value

Step 1

Concept

((x-3)(x-6)=x-2-9x+18), so (b=9). In exams (b) remains positive because the expression has (-bx).

Step 2

Why this answer is correct

The correct answer is C. (9) / correct value. ((x-3)(x-6)=x-2-9x+18), so (b=9). In exams (b) remains positive because the expression has (-bx).

Step 3

Exam Tip

((x-3)(x-6)=x-2-9x+18), इसलिए (b=9) है। परीक्षा में ऋण चिन्ह के कारण (b) धनात्मक रहता है।
