What is the value of the discriminant for the quadratic equation 0 = x + 2 + x2?

discriminant = b2 – 4ac

–9
–7
7
9

Option (b) is correct.

The discriminant for the given quadratic equation   is -7.

Step-by-step explanation:

Given quadratic equation

We have to find the discriminant for the given quadratic equation  .

Consider the quadratic equation .

The general form form of quadratic equation is , where a , b, c are the constants.

Discriminant for the general equation given by

Thus, for the given equation a= 1 , b = 1 , c = 2

Substitute , we get,

Solving we get,

Thus, the discriminant for the given quadratic equation   is -7.

Option (b) is correct.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
