How do you factor x4-x3-7x2-x+6?

Answers

Answer 1

Answer: $x^4-x^3-7x^2-x+6=x^4-x^3-6x^2-x^2-x+6=\n \n=x^2(x^2-x-6)-(x^2-x-6)=(x^2-1)(x^2-x-6)=\n \n=(x-1)(x+1)(x^2-3x+2x-6)=\n \n=(x-1)(x+1)[x(x-3)+2(x-3)]=(x-1)(x+1)(x-3)(x+2)$

Fathi wants to print out a PDF document that is 48484848 pages long. To save paper, he decides to print on both sides of each sheet and to print two pages on each side of the sheet. How many sheets of paper will he need?

Answers

Yes, as potatoelord said, divide 48,484,848 and 2.
48, 484, 848 ÷ 2 = 24, 242, 424.
This is because Fathi is using one paper for two pages.
Therefore, that is why you divide 48, 484, 848 and 2.
