Y = -x + 2 is your answer.

This is because the slope is -1 and the y-intercept is 2.

may someone help me ASAP? I am solving polynomial equations and I don't know how to do it, here is the equation... x^4+11x^2=3x^
koban [17]

<u>Answer:</u>

x=2\sqrt{2}, x=-2\sqrt{2}, x=4i, x=-4i

<u>Step-by-step explanation:</u>

x^4+11x^2=3x^2+128

First, we subtract 128 from both sides:

x^4+11x^2-128=3x^2

Then, we subtract 3x^2 from both sides:

x^4+8x^2-128=0

Rewrite the equation:

u^2+8u-128=0

Insert and solve:

u^2+8u-128=0\\u=8,u=-16\\x^2=8:x=2\sqrt{2},x= -2\sqrt{2} \\x^2=-16:x=4i,x=-4i

What is the complete factorization of the polynomial below? X3-4x^2+x-4
OLga [1]

Answer:  (x - 4)(x - (i))(x + (i))

Step-by-step explanation:

This factoring job lends itself well to synthetic division.  Looking at the constant term, -4, I came up with several possible roots based upon -4:  {±1, ±2, ±4}.  I chose +4 as my first trial root.  Sure enough, there was a zero remainder, which indicated that 4 is a root of this polynomial and (x - 4) is a factor.  The coefficients of the trinomial quotients are 1   0   1, which indicates a quotient of x^2 + 1, which has the following roots:  x = +(i) and x = -(i)

So the complete factorization of the polynomial is (x - 4)(x - (i))(x + (i)).

Can someone please tell me how to do these problems
kow [346]
These are so easy, you won't believe it !

A negative exponent only means

       "Put all of this in the denominator, and make the exponent positive."

So    (any number)^negative power =

                     1 / (the same number)^(the same power but not negative) .

The first few problems on that sheet:

1).  5^-3  =  1 / 5^3

2).  6^-10  =  1 / 6^10

3).  (-2)^-5  =  1 / (-2)^5

Got it ?    You can do the rest of them now in about 2 minutes.
