What is negative 6x squared take away 586 =84x take away 4

olchik [2.2K]

Answer:

This equation has no real roots

Step-by-step explanation:

We want to solve

$- 6 {x}^{2} - 586 = 84x - 4$

We group all terms on the left:

$- 6 {x}^{2} - 84x - 586 + 4 = 0$

$- 6 {x}^{2} - 84x - 582= 0$

Divide through by -6

${x}^{2} + 14x + 97 = 0$

The discriminant is

${14}^{2} - 4 \times 1 \times 97 = - 192$

This means the given equation has no real solution, since the discriminant is less than 0
