Answer:

\textbf{$a + bi = 2 + i$}\\

Step-by-step explanation:

\textup{Given:}\\$$\frac{4 + \sqrt{16 - (4)(5)}}{2}$$\\\textup{This can simplified as:}\\\vspace{6mm}\\

$ \frac{4 + \sqrt(-4)}{2}$\vspace{6mm}\\$\implies \frac{4 + 2i}{2}$\vspace{5mm}\\$\implies 2 \left(  \frac{2 + i}{2} \right)$\vspace{5mm}\\$$\therefore a + bi = 2 + i$$

Answer:

Quadratic Equation:

3x^2=2x +5

\text{Standard Form: } 3x^2-2x-5=0

From the standard form of a Quadratic Function, we get:

a=3,\:b=-2,\:c=-5

Discriminant:

\Delta=\left(-2\right)^2-4\cdot \:3\left(-5\right)

\Delta=\left(-2\right)^2+4\cdot \:3\cdot \:5

\Delta=64

From the discriminant, we conclude that the equation will have two real solutions.

State that:

b^2-4ac

b^2-4ac =0:\text{The equation has 1 real solution}

b^2-4ac >0:\text{The equation has 2 real solutions}

By the way, solving the equation given:

$x=\frac{2\pm\sqrt{64}}{2\cdot \:3}$

$x=\frac{2\pm\sqrt{64}}{6}$

$x=\frac{2\pm8}{6}$

$x_{1} =\frac{10}{6}=\frac{5}{3}  $

$x_{2}=\frac{-6}{6} =-1$
