Factors of 35 are 1 & 35 or 5 & 7. Can't get a -1 out of those so you have to use the quadratic formula: minus b +/- sqrt (b^2 - 4 x a x c) all over 2 x a. this gives (1 +/- sqrt (1+140) )/2 = (1 +/- 11.874)2 = 6.437 or -5.437 Check: 6.437^2 -6.437 = 41.435 - 6.437 = 34 .998. Near enough. If the original equation had been x^2 - 2x - 35 it would have factored nicely as (x + 5)(x -7)
x2-12x+35 = (x-5)(x-7)
If you mean: x2-12x+35 then it is (x-7)(x-5) when factored
xx-x-35 Factors of 35: 7*-5 -7*5 None add up to -1 Doesn't factor evenly, use quadratic
X3 X(X2) X2(X) and, X * X * X
(x+a) (x-a)
x2-12x+35 = (x-5)(x-7)
If you mean: x2-12x+35 then it is (x-7)(x-5) when factored
(x + 7)(x - 5)
Factor: x3 - 12x2 + 35x 1. Factor out a x: x(x2 - 12x + 35). 2. Factor x2 - 12x + 35 which is (x-5)(x-7). 3. Answer: x(x-5)(x-7).
X2 + 2X - 35 What two factors of - 35 add up to 2? (X - 5)(X + 7) -----------------
X2 + 2X - 35(X - 5)(X + 7)================take your pick of these two binomials
(x + 7)(x - 5)
xx-x-35 Factors of 35: 7*-5 -7*5 None add up to -1 Doesn't factor evenly, use quadratic
Answer: x (x2-x)
x2-x=x(x-1)
9 - x2 will factor into (3 - x)(3 + x)
