Question

Factor completely: x^2 − 3x + 7

I think that it is prime.

Answer 1

you are correct

Answer 2

ok great!

Answer 3

Yep :) the two factors have to be multiplied and equal 7, while add up to -3. Since 7 is a prime number, it's only 2 factors are 7 & 1, which doesn't fit into this equation. So yeah congratz ur right it's prime :)

Answer 4

Thanks!
