TO reprsent word problem in the form of quadratic equations, suppose the unknown required quantity can be taken as some variable x (say) and express the given condition in the form of x to form an equaiton in x. Then wew express the equation in the descending powers of x. Thus standard quadratic equations is ax^(2) + bx + c = 0, a != 0 . Sandeep's father is 30 years older than him.
