Question

How do you factor and solve ${x^2} + 8x = 0?$

Answer 1

Hint: these types of questions are very easy to solve if you understand the concept. So whenever you try to solve these questions or these types of questions you should understand the steps. Do not just remember. So in this question, we have to find the value of x. for that we will simplify this equation. As you can see the power of these equations is two so definitely, x will have two values.

Complete step by step answer:
In this question given equation is ${x^2} + 8x = 0$
Here, the power of the equation is two, so x has two values.
For finding those two values of x we will factorize these equations.
First, we get common x from the equation.
So after that, we get,
$x(x + 8) = 0$
Now for finding the value of x we will further factories these equations.
So $x = 0$and other is $x + 8 = 0$;
Now rearranging the equation $x + 8 = 0$we get,
$x = - 8$

So the answer to this question is $x = 0$and $x = - 8$.

Note:
You should solve this type of question very much because the concept behind it is very important and also they help you in the future to understand difficult concepts. This question is based on a very basic concept of mathematics.
