Question

If a,b,y are zeroes of cubic
y = f(x) =(x - a)(x-B)(x-»)
where
a,ß.
are in A.P. Given that a=11, B =15, and if the
a+B
tangent at p having abscissa
2 meets x-
axis at Q then PQ equals​

Answer 1

Answer:

The number of zeroes of  p(x) is the number of times the curve intersects the x-axis, i.e; attains the value 0.

Here, the polynomial p(x) meets the x-axis at 3 points.  

So, number of zeroes =3.

Step-by-step explanation:

Answer 2

Answer:

the polynimoial meets the X exist at 3 points so

number of zeroes = 3
