#numerical
A ((-3,0)) और ((3,0)) / ((-3,0)) and ((3,0))
B ((0,-3)) और ((0,3)) / ((0,-3)) and ((0,3))
C ((-9,0)) और ((9,0)) / ((-9,0)) and ((9,0))
D ((0,-9)) और ((0,9)) / ((0,-9)) and ((0,9))
Explanation opens after your attempt
Correct Answer
A. ((-3,0)) और ((3,0)) / ((-3,0)) and ((3,0))
Step 1
Concept
Solving \(x^2-9=0\) gives \(x=\pm3\). Zeroes appear on the (x)-axis as ((x,0)).
Step 2
Why this answer is correct
The correct answer is A. ((-3,0)) और ((3,0)) / ((-3,0)) and ((3,0)). Solving \(x^2-9=0\) gives \(x=\pm3\). Zeroes appear on the (x)-axis as ((x,0)).
Step 3
Exam Tip
