Find all zeros of the polynomial P(x) = x3 − 2x2 − 3x + 10. Express any non-real roots in the form a + bi.

Strike441 [17]

Answer:

$x = - 2 \: or \: x = 2 - i \: or \: x = 2 + i$

Step-by-step explanation:

The given equation is

$p(x) = {x}^{3} - 2 {x}^{2} - 3x + 10$

We can see that:

$p( - 2) = {( - 2)}^{3} - 2 {( -2) }^{2} - 3( - 2)+ 10$

$p( - 2) = - 8- 8 + 6+ 10 = 0$

This means x=-2 is a zero of p(x).

From the long division in the attachment,

We can rewrite the polynomial as:

${x}^{3} - 2 {x}^{2} - 3x + 10 = (x + 2)( {x}^{2} - 4x + 5)$

We now find solution to the quadratic part:

${x}^{2} - 4x + 5 = 0$

This is given by:

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

We plug in the values to get:

$x = \frac{ - - 4 \pm \sqrt{ {( - 4)}^{2} - 4 \times 1 \times 5} }{2 \times 1}$

$x = \frac{ 4 \pm \sqrt{ 16 - 20} }{2 }$

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

$x = \frac{ 4 \pm2i}{2 } \\ x = 2 \pm \: i \\ x = 2 - i \: or \: x = 2 + i$

Therefore all solutions are:

$x = - 2 \: or \: x = 2 - i \: or \: x = 2 + i$

Solve the following equation using algebric formulas<br> (x-y)(x+y)

photoshop1234 [79]

The simplified expression of (x + y)(x - y) is x^2 - y^2

<h3>How to solve the expression?</h3>

The expression is given as:

(x + y)(x - y)

Expand the bracket

x(x - y) + y(x -y)

Further, expand

x^2 - xy + xy - y^2

Evaluate the like terms

x^2 - y^2

Hence, the simplified expression of (x + y)(x - y) is x^2 - y^2

Answer:

(1)1 hour 15 minutes

(2)4:07

(3) 30 minutes

(4) 8:35

Step-by-step explanation:

1.We are given that

Trey and Na'Asia played basketball from 10:30-11:45

We have to find the time they play basketball.

11:45-10:30

11-10=1 hour

45-30=15 minutes

They played basketball for duration=1 hour 15 minutes

(2)

School left at 3:15

I got home 52 minutes later.

Then, I got home at =3:15+52 minutes

15 minutes+52 minutes=67 minutes

67 minutes=1 hour 7 minutes

Therefore, I got home at 4:07.

(3)

He begins making Macaroni and chees at 6:35

He finished at 7:05.

He cook his food for time =25+5=30 minutes

(4)

Mahkiya and Madison went to Cheerleading at 7:15

It was over 1 hour and 20 minutes later .

Therefore, time=7:15+1 hour 20 minutes

=(7+1) : (15+20) minutes

=8:35

Hence, it was over at 8:35.
