Question

Which expression is a quadratic binomial? x2−9x 2x4+9x2−6x−1 7x² 3x4−2x

Answer 1

x<2 -9x

Explanation:

Answer 2

Answer: FIRST OPTION

Explanation:

By definition you can classify a polynomial according to its number of terms. You can also classify it by its degree (the largest exponent is the degree).

Then, if the expression is a quadratic binomial (or a binomial of degree 2), it must have:

• Two terms.
• 2 as the largest exponent.

Therefore, based on this, you can conclude that the answer is the first option, which is shown below:

`x^(2)-9x`
