If you divide the original equation by "a", you have your answer.
30/a = (a*60)/a = 60*(a/a)
30/a = 60

Step-by-step explanation:
we have
we know that
substitute
Remember that
When multiplying decimals by 10, move the decimal point one space to the right
In this case move the decimal point eight spaces to the right
therefore
The number written in standard form is

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
