Question

which description is correct for the polynomial$4x {}^{2} + 3x - 2$a cubic trinomial b quartic trinomial c cubic trinomial d quadratic trinomial

Answer 1

4x² + 3x - 2

This is a quadratic trinomial

Explanation: A quadratic equation has 2 as its highest index power

Then a polynomial involving 3 terms is a trinomial equation.

Hence the expression

4x² + 3x - 2 has its highest index power as 2 (4x raised to the power of two) and it has three separate terms, and that makes it a quadratic trinomial.
