Without solving, find the sum & product of the roots of the following equation: -9x 2-8x = 15 Show Answer First, subtract 15 from both sides so that your equation is in the form 0 = ax 2 + bx + c rewritten equation: … To do this, we will need to rearrange the … which gives us two answers: x = -1 or x = -4. Use the quadratic formula to find the roots of this equation, and determine how many real roots the equation has. See mostly the equations can be solved by simple hit and trial and then factorisation. There are three different methods to find the roots of any quadratic equation. Solution : By comparing the given quadratic equation with the general form of quadratic equation. For a lot of quadratic functions this is the easiest way, but it also might be very difficult to see what to do. A quadratic equation with real or complex coefficients has two solutions, called roots.These two solutions may or may not be distinct, and they may or may not be real. To find the roots of a quadratic equation using Quadratic formula, all we need is to compare the given quadratic with the standard form, get the coefficients a,b,c and lastly need to plug into the quadratic formula and simplify.
