Hank factored 5n2-18n+9. His work is shown in the image. Is he correct? Why/why not?

No, he set up the number puzzle wrong and found the wrong numbers that make the product and sum.

No, he forgot to split the middle term using -15n and -3n to factor by grouping.

Yes, those are the correct values to put into each factor.

Yes, he's correct because he's a math teacher's son. ;)
