What is the first step in solving the quadratic equation -5x2+8=133?

ololo11 [35]

Answer:

b. The first step in the equation solving is subtracting 8 from both sides of the equation.

Step-by-step explanation:

Here, the given quadratic equation is : $-5x^2 + 8 = 133$

Let us try and solve this given equation.

$-5x^2 + 8 = 133 \\\implies -5x^2 + 8 - 8 = 133 -8\\\implies -5x^2 = 125\\\implies x^2 =\frac{125}{-5} = -25\\\implies x^2 = -25 = (5i)^2$

So, x = ± 5i

Hence, as we can see here, the first step in the equation solving is subtracting 8 from both sides of the equation.

17 13/18 divided by 2 7/9

erik [133]

let's firstly convert the mixed fractions to improper fractions and then divide.

$\bf \stackrel{mixed}{17\frac{13}{18}}\implies \cfrac{17\cdot 18 +13}{18}\implies \stackrel{improper}{\cfrac{319}{18}}~\hfill \stackrel{mixed}{2\frac{7}{9}}\implies \cfrac{2\cdot 9+7}{9}\implies \stackrel{improper}{\cfrac{25}{9}} \\\\[-0.35em] ~\dotfill$

$\bf \cfrac{319}{18}\div \cfrac{25}{9}\implies \cfrac{319}{\underset{2}{~~\begin{matrix} 18 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}}\cdot \cfrac{\stackrel{1}{~~\begin{matrix} 9 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}}{25}\implies \cfrac{319}{50}\implies 6\frac{19}{50}$
