Jun 30, 2018
See a solution process below:
#### Explanation:
First, rewrite each of the radicals as:
$4 \sqrt{16 \cdot 7} + 5 \sqrt{4 \cdot 14} - 9 \sqrt{9 \cdot 14}$
$\sqrt{\textcolor{red}{a} \cdot \textcolor{b l u e}{b}} = \sqrt{\textcolor{red}{a}} \cdot \sqrt{... | {} |

Why do we see a lot of oxides and fluorides bonding with f-block metals? Do they bond with polyatomic ions?
I also think $\text{PuCO}$ is not impossible (if you consider $\text{CO}$ polyatomic). I see no reason why the $\sigma$-type and $\pi$-type $f$ orbitals on plutonium can't interact with $\text{CO}$, in which $\t... | {} |

Vertex
To find the coordinates of the vertex is to substitute the axis of symmetry $y=-\dfrac{b}{2a}$ into the expression of the parabola $y=ax^2+bx+c$.
### Example 1
Find of the vertex of $y=x^2 - 4x - 3$.
### Example 2
Find the vertex of $y=2x^2 - 12x + 1$.
