Answer:
(x² - 7)(x² - 4)
Step-by-step explanation:
We can actually factor this the same way we would solve a normal quadratic equation. We will end up with the factored terms have squares of x instead of just x.
x⁴ - 11x² + 28
= x⁴ - 4x² - 7x² + 28
= x²(x² - 4) - 7(x² - 4)
= (x² - 7)(x² - 4)
7 x 2 = 14
3 x 1 = 3
14+3 = 17
answer 17 unit^2
Answer: -2/5
1. Multiply out like using distributive property
3x+6 = 4-2x
2. Now just simplify
5x+6=4
5x=-2
x=-2/5
High school gives too much homework. Studies have shown that teenagers get less sleep because they are worried about homework. On the weekdays teenagers need about eight or more hours of sleep, but because of homework they cannot. Most of the time the homework we get we won't be using; unless we go into that business. There are times homework is a waste since most people don't do it. They use a lame excuse. Homework that we get we don't remember for a test. So why get it? How come we get too much homework? We don't sleep, don't do it, forget it at home, or don't need it when we are older. There are classes let's take math for instance, we get too much a week. There might be questions we have that our parents don't know. Instead of going outside we have to do homework. High school can be tough on us high schoolers. There's a lot expected of us. Especially homework. It will give us stress and tired through the day and night. Some high schoolers even drink caffeine to keep them up to do homework. That isn't healthy for us.
Hope this helps somewhat ^^
