Answer: The equation was broken down and the simplest form was found out to be

3a²-4a+1=0

Step-by-step explanation:

This question seeks to expand your knowledge in simple Algebraic multiplication manipulations

We will tackle this with a step by step approach

Step one

Given the expression 6a-2(a-1)

Let's open up the bracket to find out what's in for us

6a-2(a-1)= 6a*a-6a*1-2*a+2*1

=6a²-6a-2a+2

=6a²-8a+2

We can further break up this equation by Factoring out a common factor which is 2

2(3a²-4a+1)=0

2=0

Or

(3a²-4a+1)=0

Sasha buys two ribbons of equal length. She cuts 9 pieces of the same length, L, from the first ribbon and finds that 5 inches a
nikitadnepr [17]

Answer:

50 inches.

Step-by-step explanation:

Let the length of the each ribbon was x.

Now, she cuts 9 pieces of same length L which means total length is 9L.

Now, doing the same she was left with 5 inches of ribbon. Hence, we have

[tex[9L+5=x.....(1)[/tex]

Similarly, we can write a equation for the second situation.

2L+40=x......(2)

From equation 1 and 2,

9L+5=2L+40\\\\7L=35\\\\L=5

Plugging this value in equation 1,

9(5)+5=x\\\\x=45+5\\x=50

Therefore, the length of each ribbon when she bought them was 50 inches.
