There are many polynomials that fit the bill,
f(x)=a(x-r1)(x-r2)(x-r3)(x-r4) where a is any real number not equal to zero.
A simple one is when a=1.
where r1,r2,r3,r4 are the roots of the 4th degree polynomial.
Also note that for a polynomial with *real* coefficients, complex roots *always* come in conjugages, i.e. in the form a±bi [±=+/-]
So a polynomial would be:
f(x)=(x-(-4-5i))(x-(-4+5i))(x--2)(x--2)
or, simplifying
f(x)=(x+4+5i)(x+4-5i)(x+2)^2
=x^4+12x^3+77x^2+196x+164 [if you decide to expand]
Answer:
75.47
Step-by-step explanation:
<em>Hey there !!!!!</em>
<em>to, see how much did the man travel in total. you just add all of the distances that the man traveled.</em>
<em>he traveled:</em>
<em>13.2 by tairn</em>
<em>45.07 by bicycle </em>
<em>17.2 by car </em>
<em>if you add all of them up :</em>
<em>45.07 + 13.2 = 58.27 </em>
<em>58.27 + 17.2 = 75.47</em>
<em>have a wonderful day </em>
Answer:
x = -9
Step-by-step explanation:
6 - 2/9x = 8
Subtract 6 from each side
6-6 - 2/9x = 8-6
-2/9 x = 2
Multiply each side by -9/2 to isolate x
-9/2 * -2/9x = 2*-9/2
x = -9
