Algebra problems to do
Introduction :
Algebra includes the topics are polynomials, factoring, Linear Equations and Inequalities and quadratic equations .The algebra is the most important part in the mathematics .every functions are presented in this area. This is the main part in algebra units. The algebra unit presents middle school level to high school level. This is help to solve for real life problem.
Algebra problems to do explanations:
Here we will learn about how to do the algebra problems
Example1:
In algebra problem for learn algebra quadratic equations
Then given equation 8x2 + 4x +1 = 0 with the standard form ax2 + bx + c = 0 and give the values of a, b and c.
Solution:
The standard form for a quadratic equation is ax2 + bx + c = 0
We compare the given equation to standard form
a = 8, b = 4 and c = 1
Example2:
Solving inequalities in algebra
Solve: │5x – 2 │ =10
Solution:
Use the result, if |x| = a, then x = a or x = -a
Here │5x – 2 │ = 10
So, it has either 5x – 2 = 10 or 5x – 2 = -10 values.
Solve every equation by the addition and multiplication philosophy.
5x = 12 , 5x = -8
After solving the equation, we get
x = `12/5` , x = `-8/5` . Answer
Problems of quadratic equation
Multiplication problems in algebra:
Example 3:
Given: 10x-2(2x+3)) +x.
Solution:
Step 1: First simplify the brackets. So we multiply (2x+3)) with 2
Step 2: So, -4x-6
Step 3: It can be written as 10x-4x-6+x
Step 4: So, the add this 10x+x-4x-6
Step5: final answer is 11x-4x-6 so, 7x-6
Algebra problems to do for practice:
Here we will do more problems in algebra
Problem1:
In algebra problems for learn algebra functions.
4x - 5 = 2x – 2
Solution:
4x - 5 = 2x – 2
Add both sides 5 we get
4x = 2x + 3
We add -2x on both sides
4x -2x= 2x -2x+ 3
2x = 3
We divide by 2 we get the final answer
2x/2 =3/2
So.x=3/2
Final answer for practice problem value X = 3/2
To solve inequalities in algebra:
problem 2:
Given:
(4x-2) (3x+15)>=0
Solution:
In this inequalities problem we find the x values
Step 1: It can be written as (4x-2) >=0, (3x+15)>=0.
Step 2: Now we need to solve x
Step 3: So, (4x-2) >=0 , (3x+15)>=0,
Step 4: So x >=2/4, x<=-15/3
Step 5: x>=1/2, x<= -5;
This is the final answer for this problem
