Question

What must be added to 3x -7 to make x2 + 4x -1?

Answer 1

Okay, here subtract the second equation by the first and simplify

Answer 2

Are you having problems with simplification?

Answer 3

I see an answer coming out there.

Answer 4

Let y represent what must be added

Then, y + 3x -7 = x^2 + 4x -1

y = x^2 + 4x -1 - 3x - (-7)

y = x^2 + x + 6

Check by adding (x^2 + x + 6) to 3x - 7 to determine if the sum is x^2 + 4x -1.
