(10v^4 + 30v^3 + 2v^2) / 10v

Zina [86]

Given expression is

$\frac{10v^4+30v^3+2v^2}{10v}$

Now we need to simplify this expression. We can begin by factoring numerator and denominator if possible.

$= \frac{2v^2(5v^2+15v+1)}{10v}$

divide numerator and denominator both by 2v

$= \frac{v(5v^2+15v+1)}{5}$

$= \frac{5v^3+15v^2+1v}{5}$

Hence final answer is $\frac{5v^3+15v^2+1v}{5}$

Or you can also keep factored form

$\frac{v(5v^2+15v+1)}{5}$

Find the number of real number solutions for the equation. x^2+5x+7=0

koban [17]

Given a quadratic equation $ax^2+bx+c=0$ , we define the discriminant as

$\Delta = b^2-4ac$

The number of real solutions of the equation depend on the sign of $\Delta$ :

If $\Delta>0$ the equation has two solutions
If $\Delta=0$ the equation has one double solution
If $\Delta$ the equation has no real solutions

In this case, we have

$\Delta = 25-28=-3$

And so this equation has no real solutions.

There are 3,072 books in the school library. There are 96 sixth graders. If the sixth graders teamed up to read all the books, h

Semenov [28]

The only thing you should do is to divide 3,072 by 96 and the answer is 32.
So each of them should read 32 books :)))
I hope this is helpful
have a nice day
