The sum of a number and its square is 42. which equation can be used to find the two numbers for which this is true? x2 + x = 42 x2 + 2x = 42 x2 + x + 42 = 0 x2 + 2x + 42 = 0

I would say the top one is correct because it says the sum is 42 so the equation has to go =42

And a number is the first part that they say. There’s nothing else with it, meaning it’s x by itself. So it’s x+ =42 to far

And it’s square is x2 so it’s x2 + x = 42
