How do I divide this?[tex] \frac{2 {x}^{3} + 3 {x}^{2} + 2 }{x + 2} [/tex]

Sagot :

From the given problem,

[tex]\frac{2x^3+3x^2+2}{x+2}[/tex]

Using synthetic division to find the quotient of the expression.

Reaarrange first the expression based on the degree from highest to smallest.

As you notice, there is no x^1 term, so we will add 0x.

[tex]\frac{2x^3+3x^2+0x+2}{x+2}[/tex]

Take the coefficients of the numerator then proceed to use the synthetic division.

The coefficients are 2, 3, 0 and 2

The last number at the lower left will be the remainder and the coefficients of the quotient are 2, -1 and 2

This will be :

[tex]2x^2-x+2-\frac{2}{x+2}[/tex]

Note that the remainder is written as r/divisor

r = -2 and the divisor is x+2

Therefore, the answer is :

[tex]2x^2-x+2-\frac{2}{x+2}[/tex]
