Answer:
two solutions : (0,-3) , (3,0)
Step-by-step explanation:
hello :
y= x² -2x -3 ...(*)
y= x -3....(**)
x²-2x-3 = x -3
x²-3x=0
x(x-3) = 0
x=0 or x-3=0
x=0 or x=3
but : y=x-3
1) x=0 y=0-3=-3
2) x=3 y=3-3=0
two solutions : (0,-3) , (3,0)
Answer:
x=-5, 7 are the excluded values
Step-by-step explanation:
Excluded values are the values that makes the denominator 0
To find excluded values we set the denominator =0 and solve for x
Factor x^2 - 2x - 35
(x-7)(x+5) =0
We set each factor =0 and solve for x
x-7 =0 so x= 7
x+5 =0 so x= -5
x=7, x=-5 makes the denominator 0
So x=7 , x=-5 are the excluded values
