Answer:
-5x+7y+7
Step-by-step explanation:
3х + 9y - 8x - 2y +7 can be written like the equation below to help solve it
3x-8x+9y-2y+7
=-5x+7y+7
Step One
Factor f(x)
f(x) = (x + 5)(x - 2)
Step Two
The zeros occur when either (x + 5) = 0 or (x - 2) = 0
x + 5 = 0
x = -5
x - 2 =0
x = 2
Step 3
Record the zeros
(-5,0) or (2,0) <<<<<< answer.
