Without any extra conditions, the answer could be 3, and the simplest polynomial with the given roots would be
(<em>x</em> + 5) (<em>x</em> - (1 + 4<em>i</em> )) (<em>x</em> + 4<em>i</em> )
= <em>x</em> ³ + 4<em>x</em> ² + (11 - 4<em>i</em> ) <em>x</em> + 80 - 2<em>i</em>
<em />
If the polynomial is supposed to have only <em>real</em> coefficients, then any complex roots must occur along with their complex conjugates:
(<em>x</em> + 5) (<em>x</em> - (1 + 4<em>i</em> )) (<em>x</em> - (1 - 4<em>i</em> )) (<em>x</em> + 4<em>i</em> ) (<em>x</em> - 4<em>i </em>)
= <em>x</em> ⁵ + 3<em>x</em> ⁴ + 23<em>x</em> ³ + 133<em>x</em> ² + 112<em>x</em> + 1360
and then the degree would be 5.
Answer:
Answer C. 350 - d
Step-by-step explanation:
If Gabe bought his baseball cards for $350, then lost d dollars when selling them, the equation would be the amount he started with minus the amount he lost giving you 350 - d.
99m I think I not sure though
Answer:
it's the last one
Step-by-step explanation:
to find the perimeter, you must add all the sides.
25 plus 25 is 50
multiple x by two for both sides and that will give you the perimeter of 70
Mean=5
Step-by-step explanation:
add the numbers given and divide it by the number of numbers given
