(x + 5)(x + 2)
(3x + 7)(2x - 9)
(x + 8)(x + 4)
It's not enough to copy the question off the test. If you don't tell us what the trinomial is, we can't factor it for you.
You need two integers that multiply to give you -42 and when added (with addition rules) a positive one. 6 and -7 would fit the bill. (x+6)(x-7)=>x^2+x-42
Factor the polynomial x2 - 10x + 25. Enter each factor as a polynomial in descending order.
