8x^2 + 6x - 5 = 8x^2 + 10x - 4x - 5 = 2x * (4x + 5) - (4x + 5) = (2x -1) * (4x + 5)
8x - 4x + 7 = 94x + 7 = 94x = 9-74x = 2x = 4/2x = 1/2x = 0.5
12x2 + 8x = 0 4x(3x + 2) = 0 Two solutions: 1. x = 0 2. x = -2/3
y=-10x-4

(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
(2x - 1)(4x + 1)
1/2x^3
x= -1
x = 1/6
8x^2 + 6x - 5 = 8x^2 + 10x - 4x - 5 = 2x * (4x + 5) - (4x + 5) = (2x -1) * (4x + 5)
16 + 2x = 10 + 8x 2x - 8x = 10 - 16 -6x = -6 x = 1 Check: 16 + 2(1) = 10 + 8(1) 18 = 18
4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
(4x + 1)(2x + 3)
4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
8x - 4x + 7 = 94x + 7 = 94x = 9-74x = 2x = 4/2x = 1/2x = 0.5
The answer is (2x^2+3)(4x+1)
