Answer:
Step-by-step explanation:
+6x-5=0
we divide the coefficient of the X by half :
in this case: 6/2 = 3 , then we do the following
The result obtained is raised to square power: 3^2=9
we sum and subtract by 9 to maintain the balance of the equation:
+6x+9-9-5=0
we have:
-9-5=0
= 14
lets apply square root on both sides of the equation:
we know:
so we have:
abs(x+3)=
from where two solutions are obtained
finally we have:
Hello,
As (2,-4) is the vertex, the parabola is y=k(x-2)²-4
As (3,-1,) is a point of the parabola:
-1=k*(3-2)²-4
==> k=3y=3(x-2)²-4 so, coefficient of x² is 3.
