(8x-1)(7x-1)
The question leaves you with the partially factored equation:
8x(7x-1) - 1(7x-1)
Now if you look at the partially factored equation, you'll see that both terms have (7x-1) as one of their factors. So let's take that (7x-1) as a factor and divide both terms by (7x-1), giving us
(8x(7x-1) - 1(7x-1)) / (7x-1)
The (7x-1) factors cancel out, leaving us with
(8x - 1)
So our 2 factors are (7x-1) and (8x-1).
Looking at the available options, the only correct one is
(8x-1)(7x-1)
Based on the distributive property of multiplication over addition. The factorized form of the given polynomial is (8x-1)(7x-1)
What is distributive property?
The distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is
A(B + C) = AB + AC
This property is known by distributive law and applies to subtraction also.
The given polynomial is [tex]56x^2 - 8x - 7x + 1[/tex]
It can be grouped and factored as
[tex]56x^2 - 8x - 7x + 1[/tex]
= [tex]8x\times 7x - 8x \times 1-7x+1[/tex]
= 8x( 7x - 1) - 1(7x - 1)
= (8x – 1)(7x – 1)
Thus, the factorized form of the given polynomial is (8x-1)(7x-1).
