PLEASE HELPP PLEASE find the zeros and factored form of c(x)=3x^2-3
Zepler [3.9K]

Answer:

3 ( x-1) (x+1) is the factored form

zeros are x=1, -1

Step-by-step explanation:

3x^2-3

Factor out a 3

3 ( x^2 -1)

What is inside the parentheses is the difference of squares

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

3 ( x-1) (x+1)

To find the zeros, set this equal to zero

3 ( x-1) (x+1) =0

Using the zero product property

x-1 =0  x+1 =0

x=1,   x=-1

ASAP! WILL MARK BRAINLIEST FOR FIRST ACCURATE ANSWER!!
snow_lady [41]

Step-by-step explanation:

3x - 2y = 12

Substituting y = 9, we find:

3x - 2 \times 9 = 12 \\  \therefore \: 3x - 18 = 12 \\ \therefore \: 3x  = 12 + 18  \\ \therefore \: 3x  = 30 \\ \therefore \: x  =  \frac{30}{3} \\ \therefore \: x  = 10 \\  \therefore \: A (...., 9) = A (10, \: 9)

Similarly, solving for point B (4, __) =B (4, 0)

Monica [59]
The answer is c because all you are doing here is subbing the variable r for 5b.
