Answer: Rico is right.
(-1)(3x + 5)²
Step-by-step explanation: If it were the difference of two squares, the -30x would not be there.
It makes sense to factor out (-1) fry the trinomial, leaving all positive terms.
Then factor 9x² + 30x + 25 as
(3x + 5)²
It’s kinda blurry I can barely even see it can you upload that worksheet again so I can do it.
1-1=0 lol how do u not know this ???
Sub in 5 for x
y=(5)2 -9
y= 10-9
y= 1
When y intercpets, x = 0
so here,
ƒ(x)=x^3-x^2-x+1
ƒ(x)=(0)^3-(0)^2-0+1
ƒ(x)= +1
