Divide x^4+3x^3-2x^2+4 by x-2<br><br>which answer shows the correct synthetic division and quotient

arsen [322]

Answer:

option-A

$\frac{x^4+3x^3-2x^2+4}{x-2}=x^3+5x^2+8x+16+\frac{36}{x-2}$

Step-by-step explanation:

we are given

divisor is

$=x^4+3x^3-2x^2+4$

Dividend is

=x-2

so, we can use synthetic division

so, we can write our expression as

$\frac{x^4+3x^3-2x^2+4}{x-2}=x^3+5x^2+8x+16+\frac{36}{x-2}$

so,

option-A

-ax+3b>5 solve for x

Dmitry [639]

$-ax+3b > 5\qquad|\text{subtract 3b from both sides}\\\\-ax > -3b+5\qquad|\text{change the signs}\\\\ax < 3b-5\qquad|\text{divide both sides by a}\\\\\text{if}\ a < 0,\text{ then}\ x > \dfrac{3b-5}{a}\\\\\text{if}\ a > 0,\text{ then}\ x < \dfrac{3b-5}{a}$
