Question

X^2 - 7x + 9 why can't this be factored?

Answer 1

The expression X^2 - 7x + 9 cannot be factored easily because the quadratic coefficient (the term in front of x^2) is 1, making it difficult to find two numbers that multiply to 9 and add up to -7. In this case, the constant term 9 does not have any factors that can be combined to get -7. As a result, this expression does not factor nicely using traditional factoring methods.
