The sum of 2 numbers is 17 and their product is 66 |
Answer» The two numbers are 11 and 6Step-by-step explanation: LET the numbers be x and y. Then ACCORDING to the condition x + y = 17 ...... eq (1) xy =66 ........ eq (2) From equation (2), we have x = 66/y Substituting the VALUE of x in eq (1) 66/y + y = 17 (66 + y2 )/y= 17 66 + y2 = 17y y2 -17y +66 = 0 Now, we need to FACTORIZE the it y2 -11y -6y +66 = 0 y(y-11) -6 (y-11) = 0 (y-11)(y-6)=0 This shows, y = 11,6
