1) Identify the roots of the quadratic function. What is the product when the roots are multiplied? A) −1 B) −6 C) 0 D) 1

D) 1

Step-by-step explanation:

Quadratic expression:-

Any equation that can be expressed in the form

where a,≠ 0 is called a quadratic equation in 'x' Here a, b ,c are called co-efficient.

Example: the quadratic expression is

here a= 1 ,b=1 and c=1

α and β are roots of the quadratic equation

sum of the two roots are α+β = -b/a = -1

product of two roots are αβ = c/a =1

There fore the product of two roots are equal to one

B. -6

i could probably can you me with a question of mine?

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
