When (11) is subtracted from the square of a number, the result is (85). What is the positive number?
Explanation opens after your attempt
Correct Answer
A. \(4\sqrt{6}\)
Concept
Let the number be (x), so \(x^2-11=85\). This gives \(x^2=96\), so the positive number is \(4\sqrt{6}\).
Why this answer is correct
The correct answer is A. \(4\sqrt{6}\). Let the number be (x), so \(x^2-11=85\). This gives \(x^2=96\), so the positive number is \(4\sqrt{6}\).
Exam Tip
मान लें संख्या (x) है, तो \(x^2-11=85\)। इससे \(x^2=96\), इसलिए धनात्मक संख्या \(4\sqrt{6}\) है।
