Answer:(X^2-11)(2X-5)
Step-by-step explanation:
2x^3-5x^2-22x+55
x^2(2x-5)-11(2x-5)
(X^2-11)(2X-5)
Answer:
.
Step-by-step explanation:

We need to find the factors of given equation;
Solution:
On Solving the above equation we get;
Now First we will take common factor from first 2 terms which is
we get;

Now we will take the common factor from the last 2 terms which is 3 we get;

Here we get 2 terms in which
is common factor.

Hence After factorizing the given equation we get
.
For polar form you need to find the modulus (length of the vector) and the argument (angle of the vector) and present in form rcis(Arg) or re^Argi
start with the modulus r=sqrt(a^2 +b^2)
=sqrt(-2^2 +2^2)
= sqrt(4+4)
=sqrt(8)
=2sqrt(2)
next the argument, firstly arg=tan(b/a)
= tan(2/2)
=tan(1)
=pi/4 . (exact values table)
Now consider the quadrant the complex number is in, as it is (-2,2) it is in the second quadrant and as such your Arg value is:
Arg=pi-arg
= pi-pi/4
= 3pi/4
add it all together and your complex number in polar form is:
2sqrt2cis(3pi/4)
note: cis is short hand for cos(x)+isin(x), it is possible your tutor would rather you use the complex exponential form which is simply re^Argi and your answer would look like:
2sqrt2e^(3pi/4)i
Also notice the difference between arg and Arg as this often slips students up and always present Arg in prinicple argument form ie -pi<Arg<pi
Hopefully this has been clear enough and good luck
Answer: 3.99797217..
Step-by-step explanation:
formula for the circumference is pi x diameter
divide circumference by pi
25.12/pi = 7.9959443...
divide that by two to get the radius which would be 3.997972...
