Question

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:

1: False

2:True

3:True(it can be logx equation also)

4:True

Step-by-step explanation:

1: if alpha + beta > 0 then -(b/a) > 0 which means eiyher b or a should be negative.

2: It can be sinx equation but not quadratic.

3:It can be logx equation also.

4:If alpha(@) and beta($) equals to zero and gamma = & then in the expression @$+$&+@&=0 which gives c/a =0 >>>c=0

and in >>>@$&=0>>>-d/a=0>>>d=0

that gives there are no constant and linear terms...
