maths inequalities...
Find the range of values of k for which the expression x^2 -4x + k will be positive for all real values of x. Hence state the range of values of x satisfying the inequality x^2 -4x + 7 > 0. For the first part, this is what i did: (-4)^2 - 4(k) > 0 k<4 but how do i do ...

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 tha...
