The equation is <span>f(x) = 2x5 - 9x4 + 12x3 - 12x2 + 10x - 3 = 0
remark:
the sum of coefficients is = 2-9+12-12+10-3=-7+7=0, so a=1 is a zero of f
f can be written as </span>f(x) = (x-1)Q(x), and f(x) / (x-1)= Q(x)
after euclid's division
Q(x) = 2x4 - 7x3 + 5x2 - 7x +3
so for finding the other roots, making Q(x) for product of factors is a must

Answer:

-2

Step-by-step explanation:

2x + y = 10               Subtract 2x from both sides.

2x-2x + y = 10 - 2x  Combine the left.

y = 10 - 2x

The slope is the number in front of the x -- in this case - 2

The answer is - 2

Rewrite the expressions below by completing the square<br> 2 + 4+ 1
Lady bird [3.3K]
STEP BY STEP EXPLANATION
(Mark brainliest pls)

Square root is 2 square + 4 square + 1 because 1 does not enable a square perhaps for negatives to be imputed, and we know 2 square will be 1 hence,

1 x 1 = 1 squared
2 x 2 = 4 squared
Perhaps for 1, you will have to use a formula equation and add tang maybe. Etc I don’t know if tang but u will also have to convert 1 to a decimal to find the square root of 1, 1 is an odd number so it will end up with remainder decimals or just do 1x1, etc.


Hence u

(2 square + 4 square) + 1square?

It depends on addition or order of operations subtraction addition or you will might use multiply
if the subject is about multiply or Division so try and do it because i don’t know if I’m right

..

REMEMBER

PEMDAS

try and solve it hope this helps!
