How do i find the roots of this equation: f(x) = 2x5 - 9x4 + 12x3 - 12x2 + 10x - 3 = 0

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

ddd [48]

Answer:

5^{9} can not be expressed as a square of any other number.

Step-by-step explanation:

The number 1953125 is equal to 5^{9}.

Now, the above statement gives an idea that 1953125 i.e. 5^{9} is not a square number as 9 is not a multiple of 2.

So, we can not express 5^{9} as a square of any other number.

We can only express 5^{9} as (5^{4} )^{2} \times 5.

PLEASE HELP ASAP CONGRUENCE IN RIGHT TRIANGLES
Pani-rosa [81]

Answer:

We know that the angles of a triangle always add up to 180 degrees, and we also know that this triangle is congruent because it has the two dashes on the side of the triangle. We also know that x is 90 degrees but this is not drawn to  scale but we can just assume it is 90 degrees.

We can tackle the triangle on the right first subtracting 47 and 90 from 180 which will give us the angle y as angle DAC is congruent to angle BAC.

180-47-90=43.

We also know that angle x is 90 degrees already or at least we assume so but to further prove our point we know that angle BCA is congruent to angle CBA which makes angle CBA 47 degrees, so subtracting 43 and 47 from 180 we have 90 degrees.

Therefore y is 43 degrees and x is 90 degrees.

it's kinda confusing ngl

*assuming that x is a right angle
