30x2-23x-14 = (6x-7)(5x+2) when factored with the help of the quadratic equation formula
5x(3x + 1)
If you mean 5x^2 -125 then it is 5(x^2 -25) when factored
-15x2+5x=-5x(3x-1)
It's a square factor.25x2-36.5x*5x 6*6Answer: (5x-6)(5x+6)
(x - 7)(x + 2)
-5x(3x - 1)
30x2-23x-14 = (6x-7)(5x+2) when factored with the help of the quadratic equation formula
5x(3x + 1)
(x + 4)(x + 1)
5x(7xy + 6x + 8)
if the x in "7x2" is variable x, then 7x(2)-5x=0 14x-5x=0 9x=0 x=0 if the x in "7x2" is a symbol for multiplication, then 7(2)-5x=0 14-5x=0 -5x= -14 5x=14 x= 14/5 x= 2 4/5 or, to factor it out... x(14-5)=0 x(9)=0 9x=0
you don't need to factor, just straight subtraction 5x-10x=-5x
7x(3x3 - 2x2 + 5x + 1)
It is: 5x
(x + 2)(x - 7)
-(x - 7)(x + 2)
