X^4-11x^2+18=0 factor

Ede4ka [16]

Answer:

(x² - 9)(x² - 2) = 0

x = 3 or √2

Step-by-step explanation:

To factor a polynomial, you need to find two expression that when multiplied together using FOIL (first, outside, inside, last) will produce the polynomial. In this case the polynomial $x^{4}-11x^{2}+18=0$ can be factored into:

(x² - 9)(x² - 2) = 0

Setting each of these expressions equal to '0':

x² - 9 = 0 or x² = 9 so √x² = √9 or x = 3

x² - 2 = 0 or x² = 2 so √x² = √2 or x = √2

Suppose that triangle ABC is a right triangle with a right angle at C and hypotenuse C. Also note that a is the length of the si

gavmur [86]

Answer:

The value of a is 7.4833. The value of $A=29.9262^0$ and $B=60.0735^0$ .

Step-by-step explanation:

Consider the provided information.

The required figure is shown below:

We need to find the value of a.

Calculate the value of a by using Pythagorean theorem.

$a^2+b^2=c^2$

$a^2+(13)^2=(15)^2$

$a^2=225-169$

$a^2=56$

$a=7.4833$

Hence, the value of a is 7.4833.

Now find the value of angle A as shown:

$\sin A=\frac{a}{c}$

$\sin A=\frac{7.4833}{15}$

$A=sin^{-1}(0.4989)$

$A=29.9262^0$

Find the value of angle B as shown:

$\sin B=\frac{b}{c}$

$\sin B=\frac{13}{15}$

$B=sin^{-1}(0.8667)$

$B=60.0735^0$

Hence, the value of $A=29.9262^0$ and $B=60.0735^0$ .

Question below :) :) :p

katrin [286]

P>7, because...
26p-20>14p+64
-14p -14p (Subtract 14 from both sides)
-----------------------
12p-20>64
+20 +20 (add 20 to both sides)
----------------
12p>84
/12 /12 (divide both sides by 12)
-----------
p>7
Hope this helps!

9+(1+43)=(19+1)+43 what property of addition is it.

Llana [10]

Answer: Associative

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

Associate is "partner". With this property the parentheses (aka partners) change but the order stays the same.

FYI: If the order changes, that is because a term moved/traveled/commuted to the other side. This is the Commutative property.
