X-5= 20
x-5= -20
Absolute value makes a negative positive, so when you are solving x-5 could have been 20 originally or -20 originally. Solve for both.
Answer:
-9,9
Step-by-step explanation:
To find the roots, we set this equal to zero
(x+9) (x-9) =0
Using the zero product property
x+9 =0 x-9=0
x =-9 x=9
Answer:
the vertex of this parabola is at (-6, 2).
Step-by-step explanation:
Compare the given y=-(x+6)² + 2 with the standard vertex form:
y = a(x - h)^2 + k. We see that
h must be -6 and k must be 2.
Thus the vertex of this parabola is at (-6, 2).
