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

Hello from MrBillDoesMath!
Answer:
x <= 3
Discussion:
The question is equivalent to
7x <= 21
Note how "not greater than" is equivalent to "less than <u>or equal to</u>"
Divide both sides of the above inequality by 7:
(7/7)x <= 21/7 =< as 7/7 = 1
x <= 3
Thank you,
