Answer:

6.  (2x - 1) 

(3x + 2)

8.  y - 3 

y² - 3y + 9

Step-by-step explanation:

6. 2x² + 9x - 5

3x² + 17x + 10

= (2x - 1) (x + 5)

3x² + 17x + 10

= (2x - 1) (x + 5)

(3x + 2) (x + 5)

=  (2x - 1) 

(3x + 2)

8. y² - 9

y³ + 27

= (y + 3) (y - 3)

y³ + 27

= (y + 3) (y - 3)

(y+3) (y² - 3y + 9)

=  y - 3 

y² - 3y + 9

lys-0071 [83]

Answer with Step-by-step explanation:

We have to prove that

$(A-B)\cup (A\cap B)=A$ is true for all sets A and B

Let $x\in(A-B)\cup (A\cap B)$

Then $x\in(A-B)$ or $x\in(A\cap B)$

$x\in A$ and $x\notin B$ or $x\in A\;and\; x\in B$

Hence, $x\in A$

Conversely ,Let $x\in A$

Then x belongs to A and x does not belongs to B then

x belongs to A- B

Or x belongs to A and x belongs to B then x belongs to $A \cap B$

Hence, $x\in( A-B)\cup (A\cap B)$

Therefore, $(A-B)\cup (A\cap B)=A$

Which equation are true for x=-2 and x=2 check all that apply

ki77a [65]

1 it is true
${x}^{2} - 4 = 0 \\ {x}^{2} = + 4 \\ x = \sqrt{4} = 2$
2 it's not true
${x}^{2} = - 4$
3 it's not true
$3 {x}^{2} + 12 = 0 \\ 3 {x}^{2} = - 12 \\ {x}^{2} = \frac{ - 12}{3} = - 4 \\$
4 it's true
$4 {x}^{2} = 16 \\ {x}^{2} = \frac{16}{4} = 4 \\ x = \sqrt{4} = 2$
5- it's true
${2(x - 2)}^{2} = 0 \\ {(x - 2)}^{2} = 0 \\ x - 2 = 0 \\ x = 2$
