Solve the equation x^6+3x^5+x^4-5x^3-6x^2-2x=0 in the real number system
koban [17]
First, pull out a factor of x.

x^6+3x^5+x^4-5x^3-6x^2-2x=x(x^5+3x^4+x^3-5x^2-6x-2)

Notice that when x=-1 (which you can arrive at via the rational root theorem), you have

(-1)^5+3(-1)^4+(-1)^3-5(-1)^2-6(-1)-2=-1+3-1-5+6-2=0

which means you can pull out a factor of x+1. Upon dividing you get

\dfrac{x^5+3x^4+x^3-5x^2-6x-2}{x+1}=x^4+2x^3-x^2-4x-2

The rational root theorem will come in handy again, suggesting that x=-1 appears a second time as a root, which means

\dfrac{x^4+2x^3-x^2-4x-2}{x+1}=x^3+x^2-2x-2

Now this is more readily factored without having to resort to the rational root theorem. You have

x^3+x^2-2x-2=x^2(x+1)-2(x+1)=(x^2-2)(x+1)

so in fact, x=-1 shows up as a root for a third time.

So, you have

x^6+3x^5+x^4-5x^3-6x^2-2x=x(x+1)^3(x^2-2)=0

Two roots are obvious, x=0 and x=-1 (with multiplicity 3). The remaining two are given by

x^2-2=0\implies x^2=2\implies x=\pm\sqrt2

What is the value of y?<br> Enter your answer in the box.
irina [24]

Answer:

Y = 64°

Step-by-step explanation:

The internal angles of a triangle sum to 180°

So by subtracting the known angles from the angle sum you can find Y

Y = 180° - 37° - 79° = 64°
