If x + y = 6 and x2 + y2 = 30, then find the product of both the variables 'x' and 'y'.

Thanks for your questions, your question is - If x + y = 6 and x2 + y2 = 30, then find the product of both the variables ‘x’ and ‘y’. Correct answer: e Now read the details Explanation for your given questions clarifications: We know the standard algebraic formula for (x+y)2 (x+y)2 = x2 + 2xy + y2 Now, according to the information given in the question, x + y = 6 and x2 + y2 = 30 Substituting these values in above equation, we get, (6)2 = 30 + 2xy ∴ 36 – 30 = 2xy ∴ 6 = 2xy ∴ xy = 3 Hence, the correct answer is option= e.
