Solve using quadratic formula pls show work

Temka [501]

Answer:

$x=\frac{3}{8},\:x=0$

Step-by-step explanation:

$x_{1,\:2}=\frac{-\left(-3\right)\pm \sqrt{\left(-3\right)^2-4\cdot \:8\cdot \:0}}{2\cdot \:8}$

$\sqrt{\left(-3\right)^2-4\cdot \:8\cdot \:0}$

$=\sqrt{3^2-4\cdot \:8\cdot \:0}$

$\sqrt{3^2}$

$x_{1,\:2}=\frac{-\left(-3\right)\pm \:3}{2\cdot \:8}$

Separate the solutions:

$x_1=\frac{-\left(-3\right)+3}{2\cdot \:8},\:x_2=\frac{-\left(-3\right)-3}{2\cdot \:8}$

$x=\frac{3}{8},\:x=0$
