i got 42 divided 7x
(4x+5)(x-3)
15xy-2xy-7x+x=13xy-6x
It is: 4x2-7x-15 when factored is (4x+5)(x-3)
(4x + 5)(x - 3)
-5
4x2-7x-15 = (4x+5)(x-3) when factored
(4x + 5)(x - 3)
x(7x ^2 - 4x + 8)
zero
-3
7x 2= 14
It is: 12x
(12x3 + 14x2 + 14x + 2)/(4x + 2) simplify= (6x3 + 7x2 + 7x + 1)/(2x + 1)1. 6x3 + 7x2 - 3x2(2x + 1) = 6x3 - 6x3 + 7x2 - 3x2 = 4x2; bring down 7x2. 4x2 + 7x - 2x(2x + 1) = 4x2 - 4x2 + 7x - 2x = 5x bring down 13. 5x + 1 - 2(2x + 1) = 5x - 4x + 1 - 2 = x - 1 the reminderThus, (6x3 + 7x2 + 7x + 1)/(2x + 1) = 3x2 + 2x + 2 + (x - 1)/(2x + 1)and(12x3 + 14x2 + 14x + 2)/(4x + 2) = 3x2 + 2x + 2 + (2x - 2)/(4x + 2).
