Multiply the polynomials (x+4)(x^2-5x+3)

Step-by-step explanation:

Write the polynomials one above the other to multiply them:

Multiply each element of by 4:

The result is: [1]

As it can be seen, only the coefficients are multiplied by 4, and when the operation involves multiplication with coefficients with different operators (+ or -), the following rules are crucial:  

That is why 4 times -5 = -20,  4 times 1 = 4, and so 4 times 3 = 12.

Multiply each element of by x:

The same rules apply here, but including the addition of powers or exponents.

The result is: [2].

or

Sum all similar terms of the previous results [1] and [2].

The result is: , because
