Factorise x^2 + 10x + 16
2 answers:
Answer:
Step-by-step explanation:
1) First, we need to see which number multiplies to 16 and adds up to 10.
By looking at the factors of 16, we can see that only 2 and 8 will work.
2) Now, we need to arrange them in the factorized equation, which is always
(x+r)(x+q).
3) This will give us our final equation:
If you want the roots, just do the negation of r and q and you will get it!

Given:
The number is .
To find:
The location of the given number of the number line.
Solution:
We have,
It can be written as
It means the number is less than -1 but more than -2. So, the number lies between -2 and -1.
The mixed fraction form of given number is
Divide the number in 5 equal parts between two consecutive integers.
Now each unit represents .
Since , therefore, it is 2 units left from -1.
The number line is given below.
