My product is 30. the differencd of the two factors is 1. the zum of the two factors is 11. what numbers am i

A * b = 30
a - b = 1
a + b = 11

take ur last 2 equations, and add them
a - b = 1
a + b = 11
add
2a = 12
a = 12/2
a = 6

now its just a matter of subbing
a + b = 11
6 + b = 11
b = 11 - 6
b = 5

so a = 6 and b = 5...whose product is 30, whose difference is 1, and whose sum is 11.

This makes absolutely no sense at all young man/women

Whose mistake? can you give more details to what the question is asking?
