Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring.
−b b^2 − 4ac 2a
use the part of the quadratic formula that you chose above and find its value, given the following quadratic equation:
2x^2 + 7x + 3 = 0

a)

b) 25

Step-by-step explanation:

a) The quadratic formula is .

The portion under the radical sign () is called the discriminant or determinant.

It tells us that, the quadratic equation can be solved by  factoring, if its value is a perfect square.

b) The given quadratic equation is .

By comparing to , we have a=2, b=7, and c=3

We substitute these values to get:

1 and 2

step-by-step explanation:

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
