Question

x2 – 9x + 20



Which represents the polynomial in factored form?



(x + 4)(x – 5)


(x – 4)(x – 5)


(x – 4)(x + 5)


(x + 4)(x + 5)

Answer 1

You can see the factors by seeing which two numbers add up to -9 and multiply to give you 20, so (x )(x ) figure out which two numbers belong there using what I said above

Answer 2

(x – 4)(x – 5)

Answer 3

yes, exactly!
