<span>His brother Noah is pulling with a force of 8 N on a bearing of 023° and his brother Jude with a force of 5 N on a bearing of 155°.</span>
Answer:
you put the variable first
Step-by-step explanation:
Jamie is correct. the reason is because when you put 7x you dont reverse it because we dont know what to multiply 7 by as when its 7x we know to multiply 7 by x
(2n^2 + 4n + 4)(4n − 5)
=(2n^2 + 4n + 4)(4n + −5)
=(2n^2)(4n) + (2n^2)(−5) + (4n)(4n) + (4n)(−5) + (4)(4n) + (4)(−5)
=8n^3 − 10n^2 + 16n^2 − 20n + 16n − 20
=8n^3 + 6n^2 − 4n − 20
The fundamental theorem of algebra states that a polynomial with degree n has at most n solutions. The "at most" depends on the fact that the solutions might not all be real number.
In fact, if you use complex number, then a polynomial with degree n has exactly n roots.
So, in particular, a third-degree polynomial can have at most 3 roots.
In fact, in general, if the polynomial has solutions , then you can factor it as
So, a third-degree polynomial can't have 4 (or more) solutions, because otherwise you could write it as
But this is a fourth-degree polynomial.
So b^2 is the sqaure of b.
so b^2 - 3
