Step-by-step explanation:

2x^{2} -16=0

+16        +16

2x^{2} =16

÷2    ÷2

x^{2} = 8

\sqrt{x^{2} }= \sqrt{8}

x= \sqrt{8}

-5x^{2} +9=0

-9          -9

-5x^{2}=-9

÷-5   ÷-5

x^{2} =1.8

\sqrt{x^{2} }= \sqrt{1.8}

x= \sqrt{1.8}

6x^{2} -15=27

+15        +15

6x^{2} =42

÷6   ÷6

x^{2} =7

\sqrt{x^{2} }= \sqrt{7}

x=\sqrt{7}

Simplify 7m - 11n - n + 5m.
goblinko [34]

Answer:

The simplified form of the given expression is 12(m -n).

Step-by-step explanation:

The given expression is

7m - 11n - n + 5m

We need to simplify the given expression.

Rearrange the terms according to the variables.

7m+5m - 11n - n

On combining like terms, we get

(7m+5m)+( - 11n - n)

On simplification, we get

(12m)+( -12n)

12m -12n

Taking GCF common.

12(m -n)

Therefore the simplified form of the given expression is 12(m -n).
