Question

The sum of two trinomials is 6x2 − 5x + 4. If one of the trinomials is 4x2 + 3x − 2, then what is the other trinomial?

10x2 + 2x − 2

10x2 + 8x − 6

2x2 − 2x + 2

2x2 − 8x + 6

Answer 1

Subtract the known trinomial from the total sum:

6x2 - 5x + 4 - 4x2 + 3x - 2 = 2X^2 -8x +6
I hope this helps :)
