10x2-36x+18 Divide all terms by 2: 5x2-18x+9 = (5x-3)(x-3) when factored
That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: (0 plus or minus 2 times the square root of 5) divided by 5. x = 0.89442719 x = -0.89442719 If you had an x in there, it would come out nicer. 5x2 + x - 4 = (x + 1)(5x - 4)
you can factorise 5x2-24x-12 if you use the quadratic formula: This goes to (24(+/-)sqrt(816))/(10) =5.257 or -0.4566 (4s.f.)
That doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (8 plus or minus 4i) divided by 5x = 1.6 + 0.8ix = 1.6 - 0.8iwhere i is the square root of negative one.
(3x + 5)(x2 - 2)
It is -50X-110.
5x2 + 3x - 1 does not have rational factors.
5x2-46x+9 = (5x-1)(x-9)
5x2 + 20x = 5x (x + 4)
x(5x + 7)
5x(x+3)
5x2-18x+9 = (5x-3)(x-3)
(x + 2)(5x + 13)
The GCF is 5x2
(x - 2)(5x + 24)
(x - 6)(5x - 6)
5x^2 + 83 is in its simplest form.
