Consider the given polynomial p(x)=30 29x - 7x^2+5x^3 + x* .4 list all possible rational roots, and factor the given polynomial

x=2, x=1, x=-5 and x=-3.

Step-by-step explanation:

Let's find the answer using the following method.

Original equation:

Notice that the constant term is 30, which can be divided by:

1, -1, 2, -2, 3, -3, 5, -5, 6, -6, 10, -10, 15, -15, 30, -30.

Trying this divisors can allowed us to find one or even two initial roots, so:

Trying first x=1, we have:

notice that x=1 is a root.

Let's try now with x=2, we have:

notice that x=2 is also a root.

So the original equation can be written as:

so:

Doing the math, we have:

now:

now:

which means:

Using the equation for calculating the roots of a quadratic equation we have:

quadratic equation:

So finally we have:

In conclusion the roots are: x=2, x=1, x=-5 and x=-3.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
