(4x - 1)(2x + 1)
What are the factors? 2x3 - 8x2 + 6x = 2x(x - 1)(x - 3).
8x2 + 2x - 1 = 8x2 + 4x - 2x - 1 = 4x(2x + 1) - 1(2x + 1) = (4x - 1)(2x + 1)
They are: (4x-5)(2x+5)
(4x - 3)(2x + 3)
8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
8x2 is 16 or 16/2=8
118x12 equals 354+1118X 12====236+118====3541. 8x2 is 16.2. You bring the 1 to 2x1.3. 2x1 is 2, add the 1 which is 3.4. Then you multiply 2x1 again which is 2.NOW YOUR ON THE ROW...1. Add the magic 0.2. Multiply 1x8=8.3. Then you will multiply 1x1 which is 1.4. Last but not least you Multiply 1x1 again, and it equals 1.5. NOW YOU ADD ALL THAT UP AND YOU GET 354
(x2 + 4 - 2sqrt(3)) (x2 + 4 + 2sqrt(3))
5-8x2-5x2 is equal to -21.
(8x2)-(13x-16)= -78
8x2 8x2
13y2 - 5yx - 8x2 = (y - x)(13y + 8x).
