Rhett is solving the quadratic equation 0= x2 – 2x – 3 using the quadratic formula. which shows the correct substitution of the values a, b, and c into the quadratic formula?

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

then the quadratic formula is

The given equation is

Here, a=1, b=-2 and c=-3.

Substitute these values in the above formula.

Therefore, the correct option is 1.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
