Answer:

The answer is A.1

Step-by-step explanation:  3(x + 1) = −2(x − 1) + 6 is turned into 3+3=−2 +2+6 once it is distributed.

then when you add the numbers you get  3+3=−2 +8

Then subtract 3 from both sides of the equation.Then simplify and add 2x to both sides and combine the like terms.

Finally your left with 5x=5 then divide and you get 1.

How do i find the roots of this equation: f(x) = 2x5 - 9x4 + 12x3 - 12x2 + 10x - 3 = 0
Fantom [35]
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
