x2 + 10 - 24 = (x + 12)(x - 2)

Factor out -1: -1(x2-3x-28) = -(x+4)(x-7) = (x + 4)(7 - x)

The value of x2+7x+10 depends on the value of X. If x=1, then x2+7x+10 = 18 If x=2, then x2+7x+10 = 28 If x=3, then x2+7x+10 = 40 and so forth

Restate the question: Factor the polynomial x2 + 7x + 10. You look for two numbers which multiply to make 10 and add to make 7. They are 5 and 2. Now put them into the two factors: (x + 5)(x + 2). Check your factors by multiplying using 'FOIL': x2 + 2x + 5x + 10 = x2 + 7x + 10. Check!

(x + 10)(x + 4)

(x + 10)(x - 6)

(x - 10)(x - 3)

x2 + 4x - 60 factors into (x + 10)(x - 6). You can use the FOIL method to check your answers when you factor.
