Answer:

2.5+7.5+-10n+-20

Step-by-step explanation:

Multiply everything on the inside by the number on the outside and put it together with addition signs.

-2.5(-3+4n+8)

-2.5*-3=7.5

-2.5(7.5+4n+8)

-2.5*4= -10

-2.5(7.5+-10n+8)

-2.5*8=-20

-2.5+7.5+-10n+-20

What is the factored form of x2 – x – 2? (x – 2)(x 1) (x 2)(x 1) (x – 2)(x – 1) (x 2)(x – 1)

Alexxx [7]

A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

<h3>What is a quadratic equation?</h3>

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.

It is written in the form of ax²+bx+c.

The factored form of the quadratic equation can be done in the following manner,

$x^2-x-2\\\\= x^2-2x+x-2\\\\=x(x-2)+(x-2)\\\\=(x+1)(x-2)$

Thus, the factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

Divide and Check...........

kirill [66]

soo this may seem a little awkwark but it still should provide the same resault however its faster :)

so we have

(48x^5-16x^3+40x)/8x

What we are going to be doing is factoring out any and all possibilities for

(48x^5-16x^3+40x)

first factor

(8x(6x^4-2x^2+5))/8x

when we get to this step simplify 8x

we are left with 6x^4-2x^2+5

in order to get an answer that would often be used by long devision just get rid of the +5

This is just a remainder using long devision your instructer may ask for

6x^4-2x^2

Hope it helps
