Question

How do you simplify the rational expression x3+x2x+1?

Answer 1

Step by step explanation :

$x \times 3 + x \times 2x + 1$

Use the commutative property to reorder the terms.

$= > 3x + x \times 2x + 1$

Calculate the product.

If a term doesn't have an exponent it is considered that the exponent is 1.

$= > 3x + x {}^{1} \times 2x {}^{1} + 1$

Multiply the terms with the same base by adding their exponents.

$= > 3x {}^{} + x {}^{1 + 1} \times 2 + 1$

Add the numbers

$= > 3x {}^{} + x {}^{2} \times 2 + 1$

Use the commutative property to reorder the terms.

$= > 3x {}^{} + 2x {}^{2} + 1$

Use the commutative property to reorder the terms.

$= > 2x {}^{2} + 3x + 1$
