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.

How do you solve this 3.7÷(1 2/9 −0.4)?

lara31 [8.8K]

3.7÷(1 2/9 −0.4) = 166.5/45 ÷ 37/45 = 4.5

0.4 = 40/100 = 2/5

2/5 = 18/45

1 2/9 = 11/9 = 55/45

55/45 - 18/45 = 37/45

3.7 = 370/100 = 18.5/5 = 166.5/45

ANSWER: 4.5
