What is the question? Do you want to factor 3x2 -x -2? If that is the question the answer is (3x + 2)(x-1)
(x + 2)(3x - 1)(3x + 1)
(x-3)(3x+1)
3x^2 -14x +15 = (3x-5)(x-3)
(3x + 1)(x - 5)
3x2 when x = 2 is the answer 3 X 4 = 12 or is the answer (3 X 2)2 = 62 = 36
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
3x2-x-2 = (3x+2)(x-1)
x(3x - 2)
(3x^(2) - 6x) / 3x Factor the numerator Hence 3x(x -2) / 3x Cancel down by '3x' Hence x -2 is the answer.
(x + 2)(3x - 1)(3x + 1)
(3x-2)(x-2)
3x2+x-2 = (3x-2)(x+1) when factored
3x^(2) +9x - 2x -6 Collect 'like terms'. Hence 3x^(2) + 7x - 6 Next write down all the factors of '3' and '6' Hence 3 ; 1' & 3' 6 ; 1,6 ; 2,3. From these pairs of number we select a pair from each coefficient, that add/multiply to '7' . Hence (3' x 3 ) & (1' x 2) ; NB 'dashes' (') to indicate source of numbers. Write up brackets (3x 2)(x 3) -2)(x + 3) Next we notice that the '6' is negative, so the two signs are different (+/-) The '7x' is positive , so the larger number takes the positive sign . Hence (3x - 2)(x + 3)
3x^2+3x-60=3(x^2+x+20)=3(x+5)(x-4)
X squared - 3x - 10 = 0 (x-5) (x+2) = 0 x - 5 = 0 x + 2 = 0 X= 5 x = -2
(x+4)(x-7)
(x-3)(3x+1)
