Answer:
Solution set= {(3,-9)}
Step-by-step explanation:
x² +6x-27=0
x² +9x-3x-27=0
x(x+9) -3(x+9)=0
(x-3)(x+9)=0
x-3=0; x+9=0
x=3; x=-9
When making a table, be on the safe side and do 2 positive and 2 negative x values.
Choose an x value and substitute it into the equation. The value of y is the y-value.
(3, 0)
(0, 1)
(-3, 2)
(-6, 3)
Then, choose two points and draw a straight line through them, you have a graph.
Hope this helps!
