<h3><u>Solution:</u></h3>Given that when 6 is subtracted from the square of a number, the result is 5 times the number
To find: negative solution
Let "a" be the unknown number
Let us analyse the given sentence
square of a number =
6 is subtracted from the square of a number =
5 times the number =
<em><u>So we can frame a equation as:</u></em>
6 is subtracted from the square of a number = 5 times the number
<em><u>Let us solve the above quadratic equation</u></em>
For a quadratic equation where
Here in this problem,
Substituting the values in above quadratic formula, we get
We have two solutions for "a"
We have asked negative solution. So a = -1
Thus the negative solution is -1
