- Linear Polynomial
The graph of a linear polynomial of the form ax+b, a not equal to zero is a straight line which intersects the x-axis at exactly one point . The value of x coordinate of the point where the line meets x- axis is zero of the polynomial.
This is a grpah of linear polynomial 2x+3. It intersects the x-axis at point (-1.5,0) .
So, the linear polynomial 2x+3 has one zero given by -1.5 (x-coordinate of point where line cuts the x-axis)
