F(x)=3x^2-18x+27<br><br>can you solve this?
Alika [10]
What do you mean by "solve this?"  Until you set f(x) = to some constant number, you don't have an equation and thus can't expect to find solutions.

Why don't we take <span>3x^2-18x+27 and set it = to 0, and only then try to solve this equation?

</span><span>3x^2-18x+27 = 0.  Dividing both sides by 3, we get x^2 - 6x + 9= 0, which can be factored as

(x-3)^2 = 0.  Taking the sqrt of both sides, we get x-3 = 0.  Actually, there are 2 roots:  3 and 3.  Again, this statement is true only if we set </span><span>3x^2-18x+27 = to 0.</span>

The expression above should be further simplified for which value of x?
stellarik [79]

Answer: A) 35

Step-by-step explanation:

We have the following:

\sqrt{215 x}

Now, 215 is made up of two factors, 43 and 5:

215=(43)(5)

So, we have to choose a number for x containing a factor of 43 and or 5. In this case, the best option is 35=(7)(5):

Hence:

\sqrt{215 (35)}=\sqrt{(43)(5)(7)(5)}

\sqrt{215 (35)}=\sqrt{(25)(43)(7)}=\sqrt{25} \sqrt{301}

Finally:

\sqrt{215 (35)}=5 \sqrt{301}
