Answer:

No real roots

$x = -2 + 4i, x = -2 - 4i$

Step-by-step explanation:

Hello!

We can solve the quadratic by using the Quadratic Formula.

Standard form of a Quadratic: $ax^2 + bx + c = 0$

Quadratic Equation: $x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}$

Given our Equation: $f(x) = x^2 + 4x + 20$

a = 1
b = 4
c = 20

Set the equation to 0 and solve using the formula.

<h3>Solve</h3>

$x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}$
$x = \frac{-4\pm\sqrt{4^2 - 4(1)(20)}}{2(1)}$
$x = \frac{-4\pm\sqrt{16 - 80}}{2}$
$x = \frac{-4\pm\sqrt{-64}}{2}$
$x = \frac{-4\pm8i}{2}$
$x = -2 + 4i, x = -2 - 4i$

There are no real roots to the quadratic.

What are the odds of getting 3 rock paper scissors in a row alike?

tensa zangetsu [6.8K]

There are 3³ possibilities for playing 3 rounds in rock paper scissors (3 choices in every round).

Draw a tree diagram of every round and (assuming that the three choices can be played in an random order as long as they are different), the options are 6.

P(RPS)=6/27=0.22

Hope I helped :)
