First step is to factorize the given expression as follows: 2x^2 + 7x - 15 = (2x-3)(x+5) This means that the two roots of the equation are 3/2 (or 1.5) and -5
Now, we will get r and s: we are given that the value of r is greater than the value of s, since 1.5 is greater than -5, therefore: r = 1.5 s = -5
