7x2-19x-6 7*6=427x2-2x+21x-6[7xx 2x] [3*7x 2*3]x(7x-2)+3(7x-2)Answer: (7x-2)(x+3)
14x2-7x2-16 7x2-16 (this can't be simplified any more)
(x - 2)(7x + 15)
x2 - 2x - 14 doesn't factor neatly. Applying the quadratic formula, we find two real solutions: 1 plus or minus the square root of 15x = 4.872983346207417x = -2.872983346207417
You need space between the numbers, I am guessing you mean 12 and 14 In which case you might factor the numbers 12=22 x3 14=7x2 So the LCM is 22 x3 x7 which is 21x4 or 84
7x2
The GCF is x2
7x2 + 68xy - 20y2
Yes, they have the common factor of 7. 14 is 7x2, 35 is 7x5
(7x2 + 9)(4x - 1)
7(x2 + 7)
I suppose you mean, how do you factor it. 7x2 - 9x - 10 = (7x + 5)(x - 2).
1. 3x2+12= 3(x2+4) 2. 7x2+35x= 7x(x+5)
I suppose that would be 14x2 - 7x3. Just take out the common factor, 7x2. Divide each term by this factor to find the other factor.
(x - 3)(7x + 2)
(7x + 4)(x - 5)
(7x + 6)(x - 2)
