X intercept polynomial
Introduction :
In mathematics, a polynomial is an expression of finite length constructed from variables (also known as indeterminates) and constants, using only the operations of addition, subtraction, multiplication, and non-negative, whole-number exponents.
For example:
2x2 - 4x + 12 is a polynomial equation.
X intercept:
x intercept is roots or zeros of the polynomial equation or function.
Steps for finding x intercept:
Example problems for x intercept polynomial
example 1:
Find the x intercept of the given polynomial function f (x) = 13x + 52
Solution:
The given polynomial equation is f (x) = 13x + 52
For finding x intercept plug f (x) = 0 in the above equation, we get
0 = 13x + 52
Subtract 52 on both the sides, we get
13x = - 52
Divide the above equation by 13 on both the sides, we get
x = - 4
Therefore, x intercept value is x = - 4
Answer:
The final answer is x = - 4.
example 2:
Find the x intercept of the given polynomial function f (x) = (x -18) (x + 10)
Solution:
The given polynomial equation is f (x) = (x -18) (x + 10)
For finding x intercept plug f (x) = 0 in the above equation, we get
0 = (x -18) (x + 10)
Equate the each factors to zero, we get
(x - 18) = 0 and (x + 10) = 0
Therefore, we get
x = 18, x = - 10
X intercepts are x = 18 and - 10
Answer:
The final answer is x = 18 and - 10
example 3:
Find the x intercept of the given polynomial function f (x) = - 2x + 40
Solution:
The given polynomial equation is f (x) = - 2x + 40
For finding x intercept plug y = 0 in the above equation, we get
0 = - 2x + 40
Subtract 40 on both the sides, we get
- 2x = - 40
Divide the above equation by - 2 on both the sides, we get
x = 20
Therefore, x intercept value is x = 20
Answer:
The final answer is x = 20.
