What are the zeros of (f(x)=x-2+8x+15)?

Explanation opens after your attempt
Correct Answer

A. (x=-3) और (x=-5)(x=-3) and (x=-5)

Step 1

Concept

(x-2+8x+15=(x+3)(x+5)). Therefore the zeros are (x=-3) and (x=-5).

Step 2

Why this answer is correct

The correct answer is A. (x=-3) और (x=-5) / (x=-3) and (x=-5). (x-2+8x+15=(x+3)(x+5)). Therefore the zeros are (x=-3) and (x=-5).

Step 3

Exam Tip

(x-2+8x+15=(x+3)(x+5))। इसलिए शून्यक (x=-3) और (x=-5) हैं।
