Answer:
(9,0) and (-4,0)
Step-by-step explanation:
First, move everything to the left to make the whole equation equal to 0.
So we get x^2-5x-36=0
Then we can factor by finding the two numbers that multiply to -36 and add to -5.
Those two numbers are -9 and 4.
So we have (x-9)(x+4)=0.
So the two roots are 9 and -4.
To verify this on a graphing calculator, plug in the equation and look at the x intercepts.
If they match up with (9,0) and (-4,0) you have your answer.
Im pretty sure its the last one. Length AB = Length A'B'
a point on the y-axis at positive 4
for the rest of the points go right 1 down 2
and left 1 up 2
