Dire.
-1
find factors of -3 (3 & -1 ) also add together to get 2 (for the 2x part) put x on both sides (x+3) (x-1) << because xsquared means x times x check it 3 times -1 = -3 3 times x = 3x -1 times x = -1x x times x = xsquared = xsquared + 2x -3 hope this helped =)
8x-4
(x + 4)(x + 1)
If you are solving for x, x2 - 2x + 1 = 0 Factor: (x-1)(x-1) = 0 Therefore: (x - 1)2 = 0 (x - 1) = 0 x = 1
4
(2x + 1)(2x + 1) or (2x + 1)2
x=1
x = 0
4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
14
(2x + 3)(x + 1 ) = 2x^2 +5x +3
