It is, as stated, x2 - 5x + 25/4 = 0
Assuming you mean x squared plus 5x squared... the answer is 6x squared.
-15x2+5x=-5x(3x-1)
The discriminant is 121.
Yes.
Factorise: 5x2 + 2x - 192 = (x - 6)(5x + 32) = 0; whence, x = 6 or -6.4.
It is a quadratic equation in the variable x.
(x + 3)(x + 2)
(x-3)(x-2)
5x=4012y=84124
That factors to (x - 2)(x + 7)
X=-3
3 + 5x = 38 -> 5x = 35 -> x = 7
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
