I have an extra credit problem for math and I have tried to solve it and cannot get past this one step.
If the sum of two numbers is 1 and the sum of the cubes of the numbers is 3, what is the sum of the squares of the numbers? (fractional answer, no decimals)
So I made two equations.
a+b=1
a^3+b^3=3
I have tried substitution and everything and I cannot get it.
