Mathematics

Answer:

(a) x² − 13x + 4

(b) x² − 26x + 153

Step-by-step explanation:

f(x) = x² + 3x − 2

a + ß = -3

aß = -2

(a) (x − a²) (x − ß²)

x² − (a² + ß²) x + a²ß²

x² − ((a + ß)² − 2aß) x + a²ß²

x² − ((-3)² − 2(-2)) x + (-2)²

x² − (9 + 4) x + 4

x² − 13x + 4

(b) (x − (a − ß)²) (x − (a + ß)²)

x² − ((a − ß)² + (a + ß)²) x + (a − ß)²(a + ß)²

x² − (a² − 2aß + ß² + a² + 2aß + ß²) x + (a² − 2aß + ß²)(a + ß)²

x² − (2a² + 2ß²) x + (a² − 2aß + ß²)(a + ß)²

x² − 2(a² + ß²) x + (a² − 2aß + ß²)(a + ß)²

x² − 2((a + ß)² − 2aß) x + ((a + ß)² − 4aß)(a + ß)²

x² − 2((-3)² − 2(-2)) x + ((-3)² − 4(-2))(-3)²

x² − 2(9 + 4) x + (9 + 8)(9)

x² − 26x + 153

2.26-30 3x+y=6<br>(0,_)<br>(_,0)<br>(3,_)<br>(6,_)<br>(5,_) ​​
bekas [8.4K]

Answer:

Step-by-step explanation:

In ordered pairs (a,b) a is the x value and b is a y value.

if we have 3x+y=6

if x=0, y=6 --> (0,6)

if y=0, x=2 -->(2,0)

if x=3, y=-3--> (3, -3)

if x=6, y= -12 --->(6, -12)

if x=6, y= -9 ---> (5, -9)

Which ordered pair makes both inequalities true?
Tatiana [17]

The ordered pair which makes both inequalities true is: D. (3, 0).

<h3>How to determine ordered pair?</h3>

In Mathematics, an inequality can be used to show the relationship between two (2) or more integers and variables in an equation.

In order to determine ordered pair which makes both inequalities true, we would substitute the points into the inequalities as follows:

At (0, 0), we have:

y > -2x + 3  

0 > -2(0) + 3

0 > 3 (false).

y < x – 2

0 < 0 - 2

0 < -2 (false)

At (0, -1), we have:

y > -2x + 3  

-1 > -2(0) + 3

-1 > 3 (false).

y < x – 2

-1 < 0 - 2

-1 < -2 (false)

At (1, 1), we have:

y > -2x + 3  

1 > -2(1) + 3

1 > -1 (true).

y < x – 2

1 < 1 - 2

1 < -1 (false)

At (3, 0), we have:

y > -2x + 3  

0 > -2(3) + 3

0 > -3 (true).

y < x – 2

0 < 3 - 2

0 < 1 (true).

Question 6 of 6
Bezzdna [24]

\huge \boxed { \sf \: Answer}

We have to use the formula:

(ab) ^{n}  =  {a}^{n}  {b}^{n}

So,

(5 \times 9) ^{12}  \\  =  {5}^{12} . 9^{12}

Also, it will be

45^{12}

Hope you could understand.
