This quadratic expression cannot be factored because its discriminant is less than zero
3x squared minus 25x minus 28
That factors to 3x(3x - 1)
If the question could more exactly be phrased as, "What is the value of x when 9x2 - 16 = 0", the answer is, x = 4 or -4. This answer can be found by factoring 9x2 - 16 into (3x + 4)(3x - 4) and setting each factor equal to zero.
(x - 4)(3x + 5)
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
(3x + 1)(x - 5)
3x(6x - 1)
x(3x - 2)
X= -2 ! Since the equation must equal zero - 17+3x must equal 11. The variable 3x HAS to equal -6... therefore x is equal to minus 2.
3x2 - 5x2 = -2x2
This quadratic expression cannot be factored because its discriminant is less than zero.
(x + 3)(3x - 2)
(3x + 8)(3x - 8)
9x2-9x-10 = (3x+2)(3x-5) when factored
3x2-x-2 = (3x+2)(x-1)
2x minus 3x is equal to -x.
3(3x + 2)(3x - 2)
3x2 - 8x = x(3x - 8)
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
3x2 -14x -24 can be factored as (3x + 4)(x - 6).
This is a difference of two squares, which factorises to: (3x - 4y)(3x + 4y)
(3x - 1)(x + 2)
