Solve: 16x^2 − 80 = 0 using the quadratic formula
round the answer to the nearest hundredth.
x = −0.45 and x = 0.45
x = −2.24 and x = 2.24
x = −8.94 and x = 8.94
x = −9.80 and x = 9.80

B

Step-by-step explanation:

Using the quadratic formula with

a = 16, b = 0 and c = - 80, then

x = ( 0 ± / 32

  = ±

x = - , x =

x = - 2.24, x = 2.24 ( to the nearest hundredth )

For this case we have the following quadratic equation:

Applying the quadratic formula we have:

Where:

Substituting we have:

We have two roots:
