### Multiplying Polynomials with Example

**Example**

**Question: Find the product of 12 + 5x and x³ + 2x² + xy + 1**

**Solution:**

Given polynomials are 12 + 5x and x³ + 2x² + xy + 1

(12 + 5x)(x³ + 2x² + xy + 1) = 12(x³ + 2x² + xy + 1) + 5x(x³ + 2x² + xy + 1)

= 12x³ + 24x² + 12xy + 12 + 5x⁴ + 10x³ + 5x²y + 5x

= 5x⁴ + 22x³ + 24x² + 5x²y + 12xy + 5x + 12

Therefore, (12 + 5x)(x³ + 2x² + xy + 1) = 5x⁴ + 22x³ + 24x² + 5x²y + 12xy + 5x + 12

### FAQs on Multiplying Polynomials Calculator

**1. How do you multiply polynomials on a calculator?**

To multiply polynomials using a calculator follow these steps. You have to enter two polynomials in the input fields and tap on the calculate button. The exact product of polynomials with an explanation will get displayed on the screen.

**2. What is the multiplication of polynomials?**

Multiplication is one of the arithmetic operations in algebra. Multiplying a thing with another means the repeated addition. In the same way polynomials, multiplication is defined as its product. So, the multiplication of two or more polynomials will be one polynomial.

**3. Solve (3x² + 2x + 1)(5x + 4)**

Given expression is (3x² + 2x + 1)(5x + 4) Multiply each term of the first polynomial with every term of the second polynomial. (3x² + 2x + 1)(5x + 4) = 3x²(5x + 4) + 2x(5x + 4) + 1(5x + 4) = 15x³ + 12x² + 10x² + 8x + 5x + 4 = 15x³ + 22x² + 13x + 4
