-(x - 7)(x + 2)
14 is not a factor, because 14 is a multiple of 7.
the greatest common factor of 14 and 70 is 14
Since the third term is negative, you need a positive and a negative factor, like this:(n + ...) (n - ...)Find two numbers that, when multiplied, give 72, and whose difference is 14. Just try the different factors of 72. If that doesn't work, use the quadratic formula. (Hint: it does work, in this case.)
The Greatest Common Factor of 14 and 44 is two.hat is the greatest comman factor for 44 and 14

3z2 + 45z + 42 = 3(z2 + 15z + 14) = 3(z + 1)(z + 14).
To factor the trinomial (7x^2 + 7x - 14), first factor out the common factor of 7: [ 7(x^2 + x - 2) ] Next, we can factor the quadratic (x^2 + x - 2) into ((x + 2)(x - 1)). Thus, the complete factorization of the original trinomial is: [ 7(x + 2)(x - 1) ]

x2+15x+14 = (x+1)(x+14)
Two numbers that multiply to give you +33 and add to give you 14 are 11 and 3. (x+11)(x+3)
