Answer:

(2x-5) (2x+5)

Step-by-step explanation:

4x^2 -25

This is the difference of squares

a^2 - b^2 = (a-b) (a+b)

(2x)^2 - 5^2

(2x-5) (2x+5)

Rewrite it in the form a^2 - b^2, where a = 2x and b = 5

(2x)^2 - 5^2

Use the Difference o Squares: a^2 - b^2 = (a + b)(a - b)

<u>(2x + 5)(2x - 5) </u>

Simplify the following expression. 3 2/5x3(-7/5)
Studentka2010 [4]

The simplified expression of 32/5 x 3(-7/5) is  -672/25

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

The mathematical expression is given as:

32/5 x 3(-7/5)

Evaluate the product of 3 and -7/5

32/5 x 3(-7/5) =  32/5 x -21/5

Evaluate the product of 32 and -21

32/5 x 3(-7/5) =  672/5 x -1/5

Evaluate the product of 5 and 5

32/5 x 3(-7/5) =  672/25 x -1

So, we have:

32/5 x 3(-7/5) =  -672/25

Hence, the simplified expression of 32/5 x 3(-7/5) is  -672/25

Which expression is equivalent to ^
mash [69]

Answer:

Step-by-step explanation:

lets break down 120 to see what it is divisible by and see if any of those numbers are perfect squares.

120/2=60

120/3=40

120/4=30

we can stop there because 4 is a perfect square and 30 can not be reduced any further to produce a perfect square.

do not forget there is only one x so it must stay in side the  radical.

your answer is 2sqrt(30x)
