Well if youre trying to simplify it then the answer would be x=12/13 or in decimal form 0.923076
4x²-36x/x-9=4x(x-9)/x-9=4x
4x=0
f(0)=0

Answer:
the exact form is 3/8
in a decimal it's 0.375
Step-by-step explanation:
The greatest common factor is 5x^2 so:
5x^2(x^2-1) (now notice that the parenthetical term is the difference of perfect squares)
The rule for factoring difference of squares is: a^2-b^2=(a-b)(a+b) so:
5x^2(x+1)(x-1)
Answer:
4
Step-by-step explanation:
y=x-8 y=-4
-4=x-8
8-4=x
4=x
