What is the factorization of the polynomial? (8x – 1)(7x – 1) (8x + 1)(7x – 1) (8x + 7x)(1 – 1)

First you simplify to 56x2 - 15x + 1.
Because of the 56, you know you will need a term with 8x and a term with 7x because 8*7=56. Answer C you can ignore because that won't give you a x^2, so it's between A and B.

The +1 in the simplified polynomial has to come from the multiplication of the numbers in the factorization. in A: -1*-1 = +1 but in B: +1*-1=-1 and that's not what we're looking for. So A is the correct answer.

Y>1 and y>x on a graph

zlopas [31]

So,

$y>1\wedge y>x$

1. Graph each inequality separately.

2. Choose a test point to determine which side of the line needs to be shaded.

3. The solution to the system will be the area where the shadings from each inequality overlap one another (purple area)

As for the system of inequalities we say it's unbounded.

Please factorize this for me

irinina [24]

9b - 12b² factorised would be 3b(3 - 4b).

You can find this as you must first find a common factor between 9b and -12b², which would be 3b. We can then take this out of the bracket and divide both terms by 3b to get the final answer, which leaves us with 3b(3 - 4b).

I hope this helps!
