<span>(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)</span>
Well, It's going to be 8/12 and then reduced it will be 4/6 or 0.667
Step-by-step explanation:
Given
sin(x) - sin(4x)
= 2 cos (( x + 4x)/2) * sin ( ( x - 4x) / 2))
= 2 cos 5x/2 • sin -3x / 2
= - 2 cos 5x/2 • sin 3x/2
