There are no rational factors.
3x squared minus 25x minus 28
x2 - 9x + 20 = (x - 4)( x - 5)
-20
(a + 3)(a - 3)
x(x - 25)(x - 25)
(5x - 2y)(5x + 2y)
Negative twenty nine minus negative twenty one is negative eight.
(x + 1)(x - 8)
To do this, first we convert to twenty-eights. That gives us eight twenty-eights minus seven twenty-eights which equals one twenty-eight.
Without that other number, all you've got is zero.
2x squared - 5x - 3 = (2x +1)(x -3)
2m^2 - 8 -First you should factor out a two. --> 2(m^2-4) -You now have something squared minus something else squared; You have m squared minus 2 squared. Whenever you have something squared minus something squared as you do in this case, there is a simple rule to remember: You can reduce that expression into the quantity of the square root of the first number or variable plus the square root of the second number or variable Times the quantity of the square root of the first number or variable minus the second number or variable squared. --> In the case of your expression: ----> 2(m+2)(m-2)<-----
