9x^2 - 25

x^2 - x - 12

anonymous · Answer

a. 9x2 – 30x + 25 was the answer

compassionate · Answer

No it wasn't. 

$$(3x - 5)^2$$
$$3x^2 - 25$$
This polynomial is not factorable with real numbers. 

Your test is messed up. 

So maybe it wants:
$$9x^2 - 25$$

Again, this polynomial isn't factorable with real numbers. 



Your test is wrong.
