Answer:
5
Step-by-step explanation:
-5 - (-10)
Here we have to use sign of multiplication rule.
negative * negative = positive
that is, -(-) = +
We use this rule and simplify.
- (-10) = + 10
Therefore, -5 + 10
When we have different sign of the numbers, we have to subtract from greatest to least number, then put the largest number sign in the answer.
-5 + 10 = + 5
Hence, the answer is 5
Hope this is will help you.
Thank you.

The solution to the equation x(x+4) = 6 is x = -2 + √10 or x = -2 - √10 after solving with the quadratic formula.
<h3>What is a quadratic equation?</h3>
Any equation of the form
where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:

We have an equation:
x(x + 4) = 6
By distributive property:
x² + 4x = 6
x² + 4x - 6 = 0
a = 1, b = 4, c = -6
Plugging all the values in the formula:

After calculating:


Thus, the solution to the equation x(x+4) = 6 is x = -2 + √10 or x = -2 - √10 after solving with the quadratic formula.
