How to do sums in algebra
Introduction :
The algebra is one of the important branch in the mathematics where we study about the rules of the various operations and then about various types of the sums with some examples. The algebra sums will be easier to understand and to solve. Now we are going to see how to do sums in algebra with various examples.
How to do sums in algebra :
Here we are going to see about the sums in the algebra with the step by step explanations as follows,
Write a verbal expression for each algebraic expression.
Example 1:
Expand the value: 122
Solution:
In this elementary algebra problem we learn how to do 122
We multiply `12xx12` finally we get answer for 122
`144` = `12xx12`
Example 2:
Solve the given inequalities in algebra
│5x – 5 │ =25
Solution:
Use the result, if |x| = a, then x = a or x = -a
Here │5x – 5 │ = 25
So, it has either 5x - 5 = 25 or 5x + 5 = 25 values.
Solve every step by the addition and multiplication principles.
`5x = 30` , `5x = - 20`
After solving the equation, we get
`x = 6` , `x = -4` .
Example 3:
Expand the expression : 9(x) 2
Solution:
Step1: First we take the root for find the factor
Step2: Take root on the both 9 and (x) 2
Step3: Finally we get the answer for 9(x) 2
`3x xx 3x=` 9(x)2

Here we see some more algebra sums for preparation
Example 1:
If x = 6, what is the value of x2 + 3x + 7?
Solution:
In this problem we learn how to do a given expression x² + 3x + 7, along with a value for x equal to 6. The exact procedure is to substitute the numerical value into the expression and then make sure to do the math correctly.
x² + 3x + 7= (6)2 + 3(6)+ 7
`36 + 18 + 7 =61`
Example 2:
4x - 5 = 2x – 2
Solution:
Add + 5 on both sides
4x = 2x
Add -2x on both sides
-2x = -2x
2x = 3
Divide by 2 on both sides we get as follows,
`(2x)/2` =`3/2`
x = `3/2`
