**weird maths sum!!**

The questions is simply: Find the range of values of x for which x(2-x)<-15 This is what i did: x(2-x)+15<0 2x - x^2 + 15 < 0 -x^2 + 2x + 15 < 0 (x+3)(-x+15) < 0 -3<x<5 but when i check by subbing the number, say, 4 into x, the answer is always greater ...

**math**

perform indicated operations. (a+3)/(5a+25)-(a-1)/(3a+15) (a+3)/5(a+5)-(a-1)/3(a+5)=(a+3)5(a+5)/5(a+5)3(a+5)-(a-1)5(a+5)/5(a+5)3(at5)= 5a^2+25a+15a+75+5a^2+25a-5a-25/5(a+5)3(a+5) i got (10a^2+60a-50)/5(a+5)3(a+5)and that's wrong. where did i go wrong?

**math-calculus**

i think i do something wrong again(2x+1)/(x-3)-(4x-1)/(2x-3) = 0 (2x-3)(2x+1)-(4x-1) = (0)(x-3)(2x-3) 4x^2+2x-6x-3-4x-1 = 2x^2-3x-6x+9 4x^2-4 = 2x^2-3x-6x+9 -2x^2-9x+13 i put this in quadratic formula and i think it wrong becaue i get 9/2 and 0for x and it have to be 2/3.
