Ex 4.4 ,2Find the values of k for each of the following quadratic equations, so that they have two equal roots. There could be no solution or an infinite number of solutions. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Your IP: 198.12.226.69 Find the values of k so that the lines described by 2x-3y=12 and kx+6y=48 are parallel. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. In each of the following find the value of ‘k’, for which the points are collinear. 1. If we define: L(alpha) = lim_(x rarr alpha) (x^2+8x+k)/(x+2) If alpha=-2 the limit exists provided k=12 => L(-2) = 4 For any other value of alpha, the limit always exist, k is arbitrary, and L(alpha) = (alpha^2+8alpha+k)/(alpha+2) The question is incomplete as the value of x is not specified for the limit. (i) (7, –2), (5, 1), (3, k) (ii) (8, 1), (k, – 4), (2, –5) The factors for are all numbers between and , which divide evenly. For the trinomial, find the value of . These values are substitued into the equilibrium expression and the value of the equilibrium constant is then calculated. Ex 4.4, 2 - Find values of k if equation has two equal roots.
