1) Find two numbers that multiply to -8 and add to 2. Factor of (-8) Sum of (2).
This is 2 * (-4)= -8 and -2 + 4= 2.
2) Then put it in factor mode. (X-2)(X+4). Use distributive property.
3) After that, set it to 0. 0= X-2 Add (+) 2 to both sides.
Cross out the negative and positive 2's. 0 + 2 is 2 = X.
4) Do the same for 4.
5) GGOD LUCK & HOPE U PASS :)

How do you factor 3x squared plus 9x minus 2x minus 6?
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)
