I NEED HELP ASAP PLEASE!!
Makovka662 [10]

Answer:

(2x-3) (2x+3)

zeros, x intercepts:  -3/2, 3/2

Step-by-step explanation:

4x^2 -9

We know the difference of squares is a^2 -b^2

This factors into (a-b) (a+b)

Let 4x^2 =a^2  

Taking the square root

2x =a

Let b^2 =9

Taking the square root

b= 3

(4x^2-9 ) = (2x-3) (2x+3)

To find the zeros, we set the equation equal to zero

(4x^2-9 ) = (2x-3) (2x+3) =0

Using the zero product property

2x-3 =0   and 2x+3 =0

2x-3+3 = 0+3                    2x+3-3 = 0-3

2x=3                                  2x=-3

Divide by 2

2x/2 = 3/2                               2x/2 = -3/2

x = 3/2                                       x = -3/2

These are the zeros of the equation (which are also the x intercepts)

Write the sum as a product of two factors 25g+10+5<br><br>​
agasfer [191]

Answer:

5\times(5g+2f+1)

Step-by-step explanation:

25g+10f+5

Writing each term in its factors:

(5\times5)g+(5\times2)f+5

We find out that 5 is the GCF of all the terms

Factoring out 5 from the given expression.

5\times(5g+2f+1)

Factors: 5 and (5g+2f+1)

Thus:

25g+10f+5 = 5\times(5g+2f+1)

Dani says she is thinking of a secret number. As a clue, she says the number is the least whole number that has three different
pychu [463]

Answer:

30 = 2 x 3 x 5

Step-by-step explanation:

The secret number is the least whole number that has three different prime factors. Since, this is the least whole number it should have the 3 smallest prime numbers as its factors.

The 3 smallest prime numbers are: 2, 3 and 5

The number that will have 2, 3 and 5 as its only factors will be the least whole number with 3 different prime factors.

So, the secret number  must be = 2 x 3 x 5 = 30
