Factor the expression 54x+81 using gfc

Answers

We can factor a binomial by taking out the gcf (common factor) . We can factor the binomial as following:

54x = 27 * 2x

81 = 27 * 3

Here, 27 is the common factor of both the terms. So, by taking out 27 as a common factor we will get,

54 x + 81

= 27 (2x + 3)

So, the factor form of the given expression is 27 (2x + 3)

Hope this helps you!

Using the given zero, find one other zero of f(x). Explain the process you used to find your solution.2 - 3i is a zero of f(x) = x4 - 4x3 + 14x2 - 4x + 13.
*Can someone show the work I have the answers

Answers

The zeros of a function are the points where the function cross the x-axis.

One other zero of \mathbf{f(x) = x^4 - 4x^3 + 14x^2 - 4x + 13} is 2 + 3i.

The zero of \mathbf{f(x) = x^4 - 4x^3 + 14x^2 - 4x + 13} is given as:

\mathbf{Zero = 2 - 3i}

The above number is a complex number.

If a complex number a + bi is the zero of a function f(x), then the conjugate a - bi is also the zero of f(x).

This means that, one other zero of \mathbf{f(x) = x^4 - 4x^3 + 14x^2 - 4x + 13} is 2 + 3i.

Answer:

One other zero is 2+3i

Step-by-step explanation:

If 2-3i is a zero and all the coefficients of the polynomial function is real, then the conjugate of 2-3i is also a zero.

The conjugate of (a+b) is (a-b).

The conjugate of (a-b) is (a+b).

The conjugate of (2-3i) is (2+3i) so 2+3i is also a zero.

Ok so we have two zeros 2-3i and 2+3i.

This means that (x-(2-3i)) and (x-(2+3i)) are factors of the given polynomial.

I'm going to find the product of these factors (x-(2-3i)) and (x-(2+3i)).

(x-(2-3i))(x-(2+3i))

Foil!

First: x(x)=x^2

Outer: x*-(2+3i)=-x(2+3i)

Inner:  -(2-3i)(x)=-x(2-3i)

Last:  (2-3i)(2+3i)=4-9i^2 (You can just do first and last when multiplying conjugates)

---------------------------------Add together:

x^2 + -x(2+3i) + -x(2-3i) + (4-9i^2)

Simplifying:

x^2-2x-3ix-2x+3ix+4+9  (since i^2=-1)

x^2-4x+13                     (since -3ix+3ix=0)

So x^2-4x+13 is a factor of the given polynomial.

I'm going to do long division to find another factor.

Hopefully we get a remainder of 0 because we are saying it is a factor of the given polynomial.

                x^2+1

              ---------------------------------------

x^2-4x+13|  x^4-4x^3+14x^2-4x+13                    

              -( x^4-4x^3+ 13x^2)

            ------------------------------------------

                                 x^2-4x+13

                               -(x^2-4x+13)

                               -----------------

                                    0

So the other factor is x^2+1.

To find the zeros of x^2+1, you set x^2+1 to 0 and solve for x.

x^2+1=0

x^2=-1

x=\pm √(-1)

x=\pm i

So the zeros are i, -i , 2-3i , 2+3i

For this question i just need help with part B. This is just the info from the question:Coach Wilson ordered t-shirts for the basketball team from two different t-shirt suppliers. One supplier charged $16 for each t-shirt as well as 5% for shipping. The other supplier charged $18 for each shirt plus 7% for shipping.

This is the question: The first supplier gave Coach Wilson a discount of 10% off of his order total. The second supplier gave him a discount for 20% off of his total order. Write an equation to find the total cost, T, of the shirts.

I know this this long and I'm sorry but pls help me

Answers

this is what i would but for it
if S is the number of shirts

supplier 1
T=16S x 1.95 x 1.9

supplier 2
T=18S x 1.93 x 1.8
