Sample questions
A quadratic polynomial can have at most how many zeroes?
A polynomial of degree n has at most n zeroes. Quadratic (degree 2) → at most 2.
If α and β are the zeroes of x² − 7x + 10, then α + β =
For ax² + bx + c, sum of zeroes = −b/a = −(−7)/1 = 7.
If α and β are zeroes of x² − 5x + 6, then α² + β² =
α + β = 5, αβ = 6. α² + β² = (α + β)² − 2αβ = 25 − 12 = 13.
