Simplify the expression using long division. (10x2 – 85x – 10) ÷ (x – 8)

Lelechka [254]

Answer: 5 • (2x2 - 17x - 2)

———————————————————

x - 8

Step-by-step explanation:

Step by step solution :

Step 1 :

Equation at the end of step 1 :

Step 2 :

10x2 - 85x - 10

Simplify ———————————————

x - 8

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

10x2 - 85x - 10 = 5 • (2x2 - 17x - 2)

Trying to factor by splitting the middle term

3.2 Factoring 2x2 - 17x - 2

The first term is, 2x2 its coefficient is 2 .

The middle term is, -17x its coefficient is -17 .

The last term, "the constant", is -2

Step-1 : Multiply the coefficient of the first term by the constant 2 • -2 = -4

Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -17 .

-4 + 1 = -3

-2 + 2 = 0

-1 + 4 = 3

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

assume that tge volume,v, of a sphere is expanding at a rate of 100 inches cubex per minute, the volume of a sphere is given by

Zielflug [23.3K]

$\bf \textit{volume of a sphere}\\\\
V=\cfrac{4}{3}\pi r^3\\\\
-----------------------------\\\\
\cfrac{dv}{dt}=\cfrac{4\pi }{3}\cdot 3r^2\cfrac{dr}{dt}\implies \cfrac{dv}{dt}=4\pi r^2\cfrac{dr}{dt}
\\\\\\
\cfrac{\frac{dv}{dt}}{4\pi r^2}=\cfrac{dr}{dt}\qquad 
\begin{cases}
\frac{dv}{dt}=100\\\\
r=8
\end{cases}\implies \cfrac{100}{4\pi 8^2}=\cfrac{dr}{dt}$

Drag the correct factors to the expression. Not all factors will be used. Use synthetic division to find all the factors of this

fiasKO [112]

The factors are therefore; (4x – 3), (x + 3) and (x – 1)

<h3>What is a polynomial?</h3>

A polynomial is is a function that contains an algebraic term which is raised to a particular power.

If it is raised to power 1 it is linear
If it is raised to power 2 it is quadratic
If its is raised to power 3 it is cubic
If it i raised to power 3 it is quartic

Now we have;

4x³ + 5x² – 18x + 9

Thus we can write;

4x³ – 3x² + 8x² – 6x – 12x + 9

Using the factors;

x²(4x – 3) + 2x(4x² – 3) – 3(4x – 3)

Therefore;

(4x – 3)(x² + 2x– 3)

(4x – 3)(x² + 3x – x – 3)

(4x – 3)(x + 3)(x – 1)

The factors are therefore; (4x – 3), (x + 3) and (x – 1)
