How Polynomial Equation Solver Calculator Works?

A polynomial is defined as a type of expression in which the exponents of the variable should be a whole number. 

A polynomial with a degree of 1 is known as a linear polynomial.

A polynomial with a degree of 2 is known as a quadratic polynomial.

A polynomial with a degree of 3 is known as a cubic polynomial.

A polynomial with a degree of 4 is known as a quartic polynomial.

A polynomial with a degree of 5 is known as a quintic polynomial.

A polynomial with a degree(n) greater than 5 is known as an nth degree polynomial.

A polynomial with any degree equates it to zero and finds the value of x for a given polynomial.

Let us understand this with the help of the following example.

Solved Examples on Polynomial Equation Solver Calculator

Example 1:

Solve the value of x for given x² - 25 = 0 and verify it using the polynomial equation solver calculator?

Solution:

x² - 25 = 0

x² = 25 

x = +5, -5

Therefore, the value of x is -5 and 5

Example 2:

Solve the value of x for given x³ + 64 = 0 and verify it using the polynomial equation solver calculator?

Solution:

x³ + 64 = 0

x³ = -64 

x³ = (-4)³

x = -4

Therefore, the value of x is -4

Now, try the polynomial equation solver calculator and find the value of x for:

• 5x⁴ - 4x + 9 = 0 
• 9x² + 4 = 0
