What is the value of discriminat for equation-3=x2+2

Discriminant = -20

Step-by-step explanation:

Discriminant of quadratic equation ax² + bx + c = 0 is given by,

Discriminant  = b² - 4ac

It is given that, a quadratic equation,

-3=x²+2

⇒ x² + 2 = -3

⇒ x² + 2 + 3 = 0

⇒  x² + 5= 0

Discriminant  = b² - 4ac

Here a = 1, b = 0 and c = 5

b² - 4ac  = 0² - 4 * 1 * 5 = -20

Therefore here the  discriminant  is a negative value

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
