### What does a 3rd degree polynomial look like?

Third-degree polynomial is of the form p(x) = ax3 + bx2+ cx + d where ‘a’ is not equal to zero.It is also called cubic polynomial as it has degree 3. Example: 5×3 + 2×2+ 3x + 7 is a cubic polynomial or Third Degree Polynomial since the highest degree of the expression is 3 or the power of the leading term is 3.

How do you find the degree of a polynomial graph?

The graph of a polynomial function will touch the x-axis at zeros with even multiplicities. The graph will cross the x-axis at zeros with odd multiplicities. The sum of the multiplicities is the degree of the polynomial function.

## How do you factor a third degree polynomial?

For sums, (x³ + y³) = (x + y) (x² – xy + y²). For differences, (x³ – y³) = (x – y) (x² + xy + y²). For example, let G(x) = 8x³ – 125. Then factoring this third degree polynomial relies on a difference of cubes as follows: (2x – 5) (4x² + 10x + 25), where 2x is the cube-root of 8x³ and 5 is the cube-root of 125.

### How do you factor a degree 3 polynomial?

#### Is Root 3 a polynomial?

Answer: Under root 3 is a polynomial and its degree is 0. This is because its expression can take place as √3(x^0).

How do you find a polynomial of degree 3 with real coefficients?

A polynomial of degree 3 has three roots and thus must be of the form a(x−r1)(x−r2)(x−r3) . We are given the roots −3 , −1 , and 4 . Thus, we just need to substitute these as r1 , r2 , and r3 . This gives us a(x+3)(x+1)(x−4) .

## How to factor a third degree poly?

Factor 3rd degree polynomials by grouping. Grouping methods can simplify the process of factoring complex polynomials. Analyzing the polynomial, we can consider whether factoring by grouping is feasible. If the polynomial is in a form where we can remove the greatest common factor of the first two terms and the last two terms to reveal another

### How to simplify polynomial equations 3rd degree?

Rearrange the expression so it’s in the form of ax3+bx2+cx+d. Let’s say you’re working with the equation: x 3 – 4x 2 – 7x+10 = 0.

• Find the all of the factors of “d”. The constant “d” is going to be the number that doesn’t have any variables,such as “x,” next to it.

– x³+x²+x+1=0 (We will suppose the value of x & check which number satisfies LHS=RHS. Let x=-1, We may put x=1,2,-3,etc.) – (-1)³+ (-1)²+ (-1)+1=0 ( After putting we will check LHS & RHS. – -1+1–1+1=0 – 0=0 (So here LHS=RHS)
