Find two numbers whose sum is 26 and whose product is 165.
Select.
A) 11 and 12	B) 11 and 13	C) 11 and 15	D) 11 and 16	E) 11 and 19
Let the two numbers be a and b and use the sum and product to write two equations with two unknowns   a + b = 26 and a b = 165   Solve the first equation for b   b = 26 - a   Substitute b in the equation a b = 165 by 26 - a   a (26 - a) = 165   Write the above equation in standard form   - a 2 + 26 a - 165 = 0   Solve the above equation for a   a = 11 and a = 15.   Use b = 26 - a to find b   when a = 11 , b = 15 and when a = 15 , b = 11.   The two numbers are 11 and 15.   Answer 11 and 15
