alleryStart learning →The zeroes of the polynomial $x^2 - 3x - 4$ are:
- 2 and −2
- 4 and −1
- 3 and 4
- −4 and 1
Show answer and solution
Correct answer: B. 4 and −1
x² − 3x − 4 = (x − 4)(x + 1), so the zeroes are 4 and −1.

A cubic (degree 3) has at most 3 zeroes.
Which of the following is NOT a polynomial?
- x² + 2x + 1
- 5
- 7x − 4
- √x + 3
Show answer and solution
Correct answer: D. √x + 3
A polynomial allows only non-negative integer exponents of x.
√x = x^(1/2) is not allowed, so it is not a polynomial.
