4 X -1 = -4 4 has the factors 1 , 4 and 2 and -2 as each will divide equally into 4 Not sure whether -1 only has -1 as a factor, I think it does as no negative number produces a negative result. -2 * -2 = 4 agreed. So I think the final answer is 1 , 2 , 4 , -2 and - 1 Regards, John O. Somewhere in the U.K.
(2x-1)(2x-1) = 4x^2 -4x + 1
It is 9*(4x + 1).
4x^(2) - 8x '4' is common to both '4' & '8' . So tak outr '4'. Hence 4(x^(2) - 2x) Inside the brackets 'x' is common to both 'x^(2) & '2x'. So take out 'x'. Hence 4x(x - 2) Done , fully factored.
(4x+1)(4x-3)
16x2 + 8x + 1 - 9y2 = (4x + 1)2 - (3y)2 which is a difference of two squares. = (4x + 1 + 3y)*(4x + 1 - 3y)
(2x-1)(2x-1) = 4x^2 -4x + 1
(2x - 1)(4x + 1)
(4x - 1)(4x + 1)
(2x - 1)(2x + 1)
4x^(2) - 8x '4' is common to both '4' & '8' . So tak outr '4'. Hence 4(x^(2) - 2x) Inside the brackets 'x' is common to both 'x^(2) & '2x'. So take out 'x'. Hence 4x(x - 2) Done , fully factored.
-1 + 4x + 6x - 20 =10x - 19
2x(2x - 1)
4(x - 1)(x + 1)
It is 9*(4x + 1).
Find factors of -5 that can be added to make -4, in this case -5 and 1, so: (x - 5)(x + 1) = x2 - 4x - 5
4x2+4x-8 4(x2+x-2) and (4x+8)(x-1)
(x - 1)(x^2 + x + 1)
