WebClick here👆to get an answer to your question ️ The ratio of the roots of the equation ax^2 + bx + c = 0 is same as the ratio of the roots of equation px^2 + qx + r = 0 . If D1 and D2 are the discriminants of ax^2 + bx + c = 0 and px^2 + qx + r = 0 respectively, then D1:D2 =
WebSquare both sides, and x^2 = 4. For some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x is only equal to 2. Therefore -2 is an extraneous solution, and squaring both sides of the equation creates them. 1 comment ( 23 votes) Upvote WebJan 15, 2024 · The formula for the root of linear polynomial such as ax + b is x = -b/a The general form of a quadratic polynomial is ax 2 + bx + c and if we equate this expression to …
