A polynomial equation with rational coefficients has the roots -8 and 2-i. Find two additional roots

shutvik [7]

Answer:

Step-by-step explanation:

If the polynomial is a cubic (third-degree), then it is

f(x) = x³+4x²-27x+40

and the other root is 2+i.

However, if we need two additional roots, it implies that the polynomial is a quartic (fourth degree). In that case, we need additional information. Reread the original question and update post if necessary.

Does anyone know the answer

Alex_Xolod [135]

Answer:x = 12,5

using thales's theorem, we have:

$\frac{15}{15+36}=\frac{20}{6x-7}\\\\ 6x-7=\frac{20.(15+36)}{15}=68\\\\x = \frac{68+7}{6}=12.5$

replace the third equation by the sum of itself and -1 times the second equation x-2y-7z=17,-6x+4y+5z=-9,8x+7y=z=-4

VMariaS [17]

Answer:

$14x+3y-6z=5$

Step-by-step explanation:

$x-2y-7z=17$ --- 1

$-6x+4y+5z=-9$ --- 2

$8x+7y-z=-4$ ---3

-1 times the second equation = $-1(-6x+4y+5z=-9)$

= $6x-4y-5z=9$ --4

Now we are given that replace the third equation by the sum of itself and -1 times the second equation

So, New third equation = $8x+7y-z+6x-4y-5z=-4+9$

= $14x+3y-6z=5$

Hence the new third equation is $14x+3y-6z=5$
