3x squared minus 25x minus 28
That factors to 3x(3x - 1)
x(3x - 2)
3x2 - 5x2 = -2x2
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
(3x-2)(x-2)
9x2-9x-10 = (3x+2)(3x-5) when factored
3x squared minus 25x minus 28
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
20x2 - 3x + 10 does not have any real factors.
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
x = 25 / 3squared + 5
The factors are [3x + 5 - 2*sqrt(10)] and [3x 5 + 2*sqrt(10)].
That factors to 3x(3x - 1)
For any x ≠ 0, x2 -10/x2 - 4 +3x/x2 - 4 LCD = x2, multiply each term by their missing element of LCD = (x4 + 10 +3x - 8x2)/x = (x4 - 8x2 + 3x + 10)/x2
(x-3)(3x+1)
x(3x - 2)
