 Hello and welcome to the session. In this session, we will discuss a question which says that using a quadratic formula, solve the following equation for x. e to the x square plus v square minus ac the whole into x minus bc is equal to 0. Now before starting the solution of this question, we should know our result. And that is for a quadratic equation, ax square plus bx plus c is equal to 0, where a is not equal to 0 and a basically are the constants. The quadratic formula for finding all the rules of this equation is, x is equal to minus b plus minus square root of b square minus 4 ac. Now this result will work out as a key idea for solving out the solution. Here we have to solve this quadratic equation. So given the quadratic equation as b square minus ac the whole into h minus bc is equal to 0. Now comparing this equation with the equation written in the key idea, here b is equal to b square minus ac and c is equal to minus bc. And the value of b square minus 4 ac is of b, a and c here. It will be b square minus ac whole square minus whole into a b into minus bc is equal to b whole square plus a square c square if it will be plus a b square c is equal to b whole square plus a square c square. And this will become, which can further be written as b whole square plus a whole square plus b square is equal to b whole square plus ac whole square. Whole square is a square plus b square plus 2 a b. So here the formula is completed. So this will be equal to b square plus ac whole square. Now using the quadratic formula, which is given with a key idea, minus b plus minus square root of b square. Now this is the value of b square minus 4 ac. So putting all these values here, this implies x is equal to minus f b square minus ac whole, plus minus minus b square plus minus b square root minus b square plus ac plus b square plus ac whole square minus b square minus ac whole square. Now here, this will be cancelled with this. So it will be, this will be cancelled with this. So it will be minus b square minus b square root upon 2 a b. Now this implies minus b square is equal to minus 2 b square over 2 a b. This is equal to, here 3 will be cancelled with 2, a will be cancelled with a. So it will be c over b and all these terms, this will be minus b over a. And you should not give a question and that's all for this session. Hope you have enjoyed the session.
