Answer:

-x² + y² + 2xy - 5yz

Step-by-step explanation:

"A" must be added to first expression to get the second one:

A + 2x² - 3 xy + 5yz = x² - xy + y²
A = ?

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

A = x² - xy + y² - (2x² - 3 xy + 5yz) =
x² - xy + y² - 2x² + 3 xy - 5yz=
-x² + y² + 2xy - 5yz

Which radical expression is an irrational number? A. √ 121 B. √ 65 C. √ 36 D. √ 64

alina1380 [7]

We will verify each options

option-A:

$\sqrt{121}$

we can factor it

$\sqrt{121}=\sqrt{11*11}$

$\sqrt{121}=\sqrt{11^2}$

$\sqrt{121}=11$

so, this is not irrational.........Answer

option-B:

$\sqrt{65}$

Since, it can not be factored

so, this is irrational.........................Answer

option-C:

$\sqrt{36}$

we can factor it

$\sqrt{36}=\sqrt{6*6}$

$\sqrt{36}=\sqrt{6^2}$

$\sqrt{36}=6$

so, this is not irrational.........Answer

option-D:

$\sqrt{64}$

we can factor it

$\sqrt{64}=\sqrt{8*8}$

$\sqrt{64}=\sqrt{8^2}$

$\sqrt{64}=8$
