Question

is 3x^2+2x^2+x a polynomial function

Answer 1

Step-by-step explanation:

3x^2+2x^2+x

=5x^2+×

this is a quadratic polynomial.

Answer 2

Answer:

$\large\boxed{5x^2+x=x(5x+1)}$

Step-by-step explanation:

To solve this problem, first you have to isolate by the x on one side of the equation.  You can also used polynomial function of f(x).

Given:

3x²+2x²+x

Solutions:

First, you have to add the numbers from left to right.

Then, add similar elements from left to right numbers.

$\displaystyle 3x^2+2x^2+x=\boxed{5x^2+x}$

You can also solve the factors of 5x²+x.

$\large\boxed{\textnormal{Distributive property}}$

$\displaystyle a(b+c)=ab+ac$

$\large\boxed{\textnormal{Exponent Rule}}$

$\displaystyle a^b^+^c=a^ba^c$

Solve.

$\displaystyle xx=x^2$

$\displaystyle 5xx+x$

Factor it out by the common term of x.

$\displaystyle 5xx+x=\boxed{x(5x+1)}$

Therefore, the correct answer is 5x²+x or x(5x+1).
