How many real solutions does x²+8x+20=0 have?

garri49 [273]

Answer:

No real solutions

Step-by-step explanation:

Use the discriminant formula, D = b² - 4ac

D = b² - 4ac

Plug in b, a, and c:

D = b² - 4ac

D = (8)² - 4(1)(20)

D = 64 - 80

D = -16

Since the discriminant is negative, there are no real solutions

In mathematics, the distance between one point (a) and another point (b), each with coordinates (x,y), can be computed by taking

anygoal [31]

The formula to find the distance between points $P_{1}$ and $x_{2}$ is given as $\sqrt{ ( y_{1}- y_{2}) ^{2}+ ( x_{1}- x_{2}) ^{2} }$ , where

$y_{1}- y_{2}$ is the vertical distance between two points on the y-axis
$x_{1} - x_{2}$ is the horizontal distance between two points on the x-axis
