(7x-3)(2x+5) 14x2 + 29x - 15, write 29x = 35x - 6x = 14x2 - 6x + 35x - 15 = (14x2 - 6x) + (35x - 15) = 2x(7x - 3) + 5(7x - 3) = (7x-3)(2x+5)
x3 + 2x2 - 35x = x(x + 7)(x - 5)
That depends on what you mean by "6x 5", which could be 6x * 5, 6x + 5, 6x - 5, 6x / 5, 6x5, etc.
3/7x + 5 = 87x(3/7x + 5) = 8(7x)3(7x/7x) + (7x)(5) = 8(7x)3 + 35x = 56x3 + 35x - 35x = 56x - 35x3 = 21x3/21 = 21x/211/7 = x
24ab - 42ax - 20b + 35x = 6a(4b - 7x) - 5(4b - 7x) = (4b - 7x)(6a - 5)
(7x-3)(2x+5) 14x2 + 29x - 15, write 29x = 35x - 6x = 14x2 - 6x + 35x - 15 = (14x2 - 6x) + (35x - 15) = 2x(7x - 3) + 5(7x - 3) = (7x-3)(2x+5)
14x2 + 29x - 15= 14x2 + 35x - 6x - 15= 7x(2x + 5) - 3(2x + 5)= (2x + 5)(7x - 3)

6x - 5 -5 = 0 6x -10 = 0 +10=+10 6x=10 x= about 1.4
6x-5 = 7, 6x = 7+5, 6x = 12, x = 2
5-6x=5 -6x=0 X=undefined There is no answer its a trick question
