Answer:
the "negative solution" is -3
Step-by-step explanation:
Represent the number by n.
Then n^2 - 24 = 5n
We rewrite this in standard quadratic form:
n^2 - 5n - 24 = 0
This factors as follows; (n + 3)(n - 8) = 0
The roots are n = -3 and n = 8. Thus, the "negative solution" is -3
The correct answer is -3
What is quadratic equation?
The equation having the highest degree 2 of a variable is known as quadratic equation.
How to find the roots of the quadratic equation?
The roots of the equation can be find by following steps
- The roots of the equation can be found by splitting the middle term.
- Take the product of the coefficient of the first term and the last term
- Split the middle term by sum of the product.
- After splitting the middle term the equation will have 4 terms and then take the common factors.
- Find the two root.
How to solve the problem?
Let us assume the number to be x
So, According to the statement
the difference of the square of the number and 24 is [tex]x^{2}-24[/tex]
is equal to 5 times that number is [tex]5x[/tex]
So the equation will be [tex]x^{2} -24=5x\\[/tex]
Therefore ,
[tex]x^{2} -5x-24=0\\x^{2} +3x-8x-24=0\\\x(x+3)-8(x+3)=0\\(x+3)(x-8)=0[/tex]
Therefore , x = -3 or x = 8
Hence the negative solution is -3
