Find all the zeros of the polynomial function P(x) x^4-4x^3 -5x^2+38x- 30

worty [1.4K]

Answer:

The zeros of the polynomial function are 1, -3, 3+i and 3-i.

Step-by-step explanation:

The given function is

$P(x)=x^4-4x^3-5x^2+38x-30$

We can find a zero of the given function by hit and trial method.

Substitute x=1 in the given function.

$P(1)=(1)^4-4(1)^3-5(1)^2+38(1)-30$

$P(1)=0$

The value of function is 0 at x=1 it means (x-1) is a factor of given function.

Substitute x=-3 in the given function.

$P(-3)=(-3)^4-4(-3)^3-5(-3)^2+38(-3)-30$

$P(-3)=0$

The value of function is 0 at x=-3 it means (x+3) is a factor of given function.

$(x-1)(x+3)=x^2 + 2 x - 3$

Divide the given function by $x^2 + 2 x - 3$ , to get remaining factors.

$\frac{x^4-4x^3-5x^2+38x-30}{x^2 + 2 x - 3}=x^2 - 6 x + 10$

So, the factor form of given function is

$P(x)=(x - 1) (x + 3) (x^2 - 6 x + 10)$

Quadratic formula: If a quadratic equation is $ax^2+bx+c=0$ , then

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

Using quadratic formula find the zeroes of $x^2 - 6 x + 10$ .

$x=\frac{-(-6)\pm \sqrt{(-6)^2-4(1)(10)}}{2(1)}$

$x=\frac{6\pm \sqrt{-4}}{2}$

$x=\frac{6\pm 2i}{2}$ $[\because \sqrt{-1}=i]$

$x=3\pm i$

Therefore the zeros of the polynomial function are 1, -3, 3+i and 3-i.

Ivan

The sunglasses were originally priced at $ 21.

Given that Lori brought sunglasses and flip-flops at a half-off sale, to determine, if she spent a total of $ 21 on the two items, what was the original price of the sunglasses (taking into account that they both cost the same) will be you must perform the following calculation:

50 = 21
100 = X
100 x 21/50 = X
2100/50 = X
42 = X

Thus, the total price of both goods is $ 42, which, divided in half, results in $ 21 (42/2).

Therefore, the sunglasses were originally priced at $ 21.

Identify the properties used in step 1 and step 2 to solve the equation shown 2x+6=22 then discuss why those properties were use

Jet001 [13]

Answer:

In step 1 subtraction property is used and in step 2 division property is used.

Explanation:

We have the equation 2x + 6 = 22

Step 1

The subtraction property of equality tells us that subtracting the same number to each side of an equation gives us an equivalent equation

So subtracting 6 from both sides

2x + 6 - 6 = 22 - 6

2x = 16

Step 2

The division property of equality tells us that you can divide each side of an equation with the same nonzero number to produce an equivalent equation

So dividing each side by 2.

$\frac{2x}{2} =\frac{16}{2} \\ \\ x=8$
