Question

Draw the solution point, or points, for this system of equations. y=2x^2-12x+20 y=2

Answer 1

Answer:

Step-by-step explanation:

hello :

you have this system :      y=2x²-12x+20

                                          y=2

means :   2x²-12x+20 =2

2x²-12x+20-2 =0

2x²-12x-18 =0        a=2  and b= -12   and c= -18

delta = b²-4ac

delta = (-12)²-4(2)(-18)

delta = 0

X1 =X2 = -b/2a =12/4 =3

the solution point is : (3 ; 2)
