Question

Solve each quadratic equation using the Quadratic Formula.

Answer 1

x=-4+-√4²-4(5)(0)
------------------------
2(5)

x=-4+-16
------------
10


-20
----
10

x=-2

-4+16
---------
10

x=1.2

Answer 2

`x = -\frac45, x = 0`

Explanation:

Hello!

To solve this, we have to simplify the radical and fraction.

Simplify:

• 
  `x = (-4 \pm√(4^2 - 4(5)(0)))/(2(5))`
• 
  `x = (-4 \pm √(16))/(10)`
• 
  `x = (-4 \pm 4)/(10)`
• 
  `x = -\frac45, x = 0`

There are two solutions for x: -0.8, and 0.
