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

___________________________________________

Explanation:
____________________________________________
Given:   (9 * 10⁻⁵) * (5 *10 ⁻⁶) ;   Simplify.
____________________________________________
 (9 * 10⁻⁵) * (5 *10⁻⁶)  =

9 * 5 * 10⁻⁵ * 10⁻⁶ = 

(9 * 5) * 10⁻⁵ * 10⁻⁶ 

45 * 10⁻⁵ * 10⁻⁶  ;   
______________________________________
Note the following property of exponents:

xᵃ * xᵇ = x⁽ᵃ⁺ᵇ⁾ ;

As such, 10⁻⁵ * 10⁻⁶ = 10⁽⁻⁵ ⁺ ⁻⁶) = 10 ⁻¹¹ ;
______________________________________
So;  45 * 10⁻⁵ * 10⁻⁶ 

           =  45 * 10⁻¹¹ .
