Question

Which algebraic expression is a trinomial? x3 + x2 – 2x3 – x2 4x3 + x2 – x6 – x +

Answer 1

3x+2x=5x
-2*3=-6
24*3=76
2x-6x-x=-5
so, 5x-6+76-5
5x+65

Answer 2

Answer:

Step-by-step explanation:

Which algebraic expression is a trinomial? x3 + x2 – 2x3 – x2 4x3 + x2 – x6 – x +

x³ + x² - 2x³ - x²

= -x³

it consist of single term

so it is a monomial

4x³ + x² - x⁶ - x

= -x⁶ + 4x³ + x² - x

Consist of four terms so not a trinomial
