Plz help me Use the discriminant to determine The number of solutions to the quadratic equation -x^2+10x-2=0

x=-5

Step-by-step explanation:

i just solved the problem

=5±√23

Step-by-step explanation:

        -10+2√23

=

               -2

         -10-2 √23

=

                -2

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.
