Solving a Polynomial Equation by Factoring
You can select either factorization or synthetic division method to solve polynomial equations. The simple steps to solve your equation using factoring is mentioned here. You must follow these steps while solving polynomial equations.
- Take any polynomial equation.
- Bring all the variable values to one side and the other side should be zero.
- If the equation is in the form of axn+axn-1+axn-2--ax=0, separate one x from the equation
- Find the each value of x by finding the factors.
How to Solve Polynomial Equation using Synthetic Division Method
- Consider any polynomial equation
- Get all the variables of the equation to one side
- Find out the one number that satisfies your equation by checking the factors of constant
- Take all the coefficients of the equation
- Write the first number as it as and follow the division method for remaining coefficients
- The last value automatically becomes zero
- Write an equation using the obtained values
- Repeat the same process to find other values
Examples:
Question1: Solve x4-2x3-13x2+14x+24=0 using a synthetic division method?
Answer:
Given equation is x4-2x3-13x2+14x+24=0
The factors of 24 are +-1, +-2, +-3, +-4, +-6, +-8, +-24
By substituting the -1 in the equation
(-1)4-2(-1)3-13(-1)2+14(-1)+24=0
-1+2-13+-14+24=0
So -1 is the factor of the above equation and we can use synthetic division method
The coefficients of the equation are 1,-2,-13,14,24
Synthetic Division Method is
-1 1 -2 -13 14 24
-1 3 10 -24
1 -3 -10 24 0
(x+1)(x3-3x2-10x+24)=0
The coefficients of x3-3x2-10x+24 are 1, -3, -10, 24
Substitute 2 in the equation
(2)3-3(2)2-10(2)+24=0
8-12-20+24=0
So, 2 is another factor for the given equation
By Synthetic Division Method
2 1 -3 -10 24
2 -2 -24
1 1 -12 0
(x+1)(x-2)(x2+x-12)=0
(x+1)(x-2)(x2+4x-3x-12)=0
(x+1)(x-2)(x-4)(x+3)=0
The values of x are -1, 2, 4, -3.
Question2: Solve x3-3x2-4x+12=0 using factorization?
Solution:
Given equation is x3-3x2-4x+12=0
x(x2-3x)-4(x-3)=0
(x-3)(x2-4)=0
The values of x are 3, -2, 2.
