Answer: x= 1, \frac{1}{5\\}

Step-by-step explanation:

The quadratic equation is

x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}

and

x=\frac{-b-\sqrt{b^{2}-4ac } }{2a}

So we just need to sub in the proper numbers from the equation given, in this case, it would result in

x=\frac{6+\sqrt{(-6)^{2}-4(5)(1) } }{2(5)}

and

x=\frac{6-\sqrt{(-6)^{2}-4(5)(1) } }{2(5)}

Once we get this we can either manually simplify or use a calculator, using a calculator would result in the answers

x= 1, \frac{1}{5\\}

Which number in the monomial 215x^18y^3z^21 needs to Be changed to make it a perfect cube ?
FinnZ [79.3K]

Hello from MrBillDoesMath!

Answer:  215

Discussion:

Let's start by rewriting the monomial as

215  x^18 y ^3 z^21

Now..

x^ 18 = (x^6)^3

y^3   = (y    )^3

z^21 =  (z^7)^3

So those terms are already cubes!  The only remaining candidate is the number 215, which is not a cube.




Thank you,

MrB
