Answer: FIRST OPTION
Step-by-step explanation:
<h3>
The missing picture is attached.</h3>
By definition, given a Quadratic equation in the form:
Where "a", "b" and "c" are numerical coefficients and "x" is the unknown variable, you caN use the Quadratic Formula to solve it.
The Quadratic Formula is the following:
In this case, the exercise gives you this Quadratic equation:
You can identify that the numerical coefficients are:
Therefore, you can substitute values into the Quadratic formula shown above:
You can identify that the equation that shows the Quadratic formula used correctly to solve the Quadratic equation given in the exercise for "x", is the one shown in the First option.

Step-by-step explanation:
Cube each portion:
SAS theorem states that if <u>two sides</u> and the <u>included angle</u> of one <u>triangle</u> are <u>congruent</u> to <u>two sides</u> and the <u>included angle</u> of another <u>triangle</u>, then these two <u>triangles are congruent</u>.
1. RQ ≅ QP (given)
2. If RP bisects ST at Q, then TQ ≅ QS (by the definition of segment bisector).
3. ∠RQT, ∠PQS are vertical angles (angles that are vertically opposite to each other when lines PR and ST intersect, Q is the common vertex).
∠RQT ≅ ∠PQS (by the vertical angles theorem).
Vertical angles theorem states that vertical angles are always congruent.
According to SAS theorem, ΔRQT ≅ ΔPQS.
Answer: vertical angles theorem
Just substitute each values into x^2+y^2+ 2gx+2fy=0
then solve simultaneously
then substitute the values
