Are the following statements true or false? Justify your answer.
1— If the zeroes of a quadratic polynomial ax2 + bx + c are positive, then a, b and c all have the same sign
2— if the graph of a polynomial intersects three x axis at only one point, it cannot be a quadratic polynomial
3— if the graph of a polynomial intersects the x axis at exactly two points, or need not to be a quadratic polynomial
4— if two of the zeroes of a cubic polynomial are zero, then it does not have linear and constant term

Answer 1

Answer:

yes true these are the rules of quadratic equations
