(4+x) (2x-3)
x2 - 2x = x(x - 2)
x(4x-2)
0.4306
(2x - 1)(x + 3)
33
-8i
if you mean (3/(2x-5))(21/(8x2-14x-15)) you would get (63/( (2x-5)(4x+3)(2x-5) ) simplified more would be 63/ ( (2x-5)2(4x+3) )

It is: x-1+4+7x-3 = 8x simplified
x^2 - y^2 - 4 is in its simplest form.
(4x-8)(2x+2)
(4+x) (2x-3)
Using the quadratic formula-- ((negative b plus or minus the square root of b squared minus 4ac) divided by (2a)) you'll want to google that so you can see it in numerical form. a, b, and c are the coefficiants of your three terms ( 2 is a, -5 is b, and 2 is c) The answer is (x-2)(2x-1).
x2 - 2x = x(x - 2)
x(4x-2)
