Question

The graph of polynomial p(x) crosses the X-axis at (-4,0). What is the zero of p(x)? ​

Answer 1

$\sf{ \underline{SOLUTION}}$

GIVEN

The graph of polynomial p(x) crosses the X-axis at (-4,0).

TO DETERMINE

The zero of p(x)

EVALUATION

The zero of a polynomial is the the value of x for which p(x) = 0

Graphically, the zero of a polynomial is the Abscissa of the point where the graph of the polynomial cut x axis

Here it is given that the graph of polynomial p(x) crosses the X-axis at (-4,0)

So one of the zeroes of the polynomial p(x) is - 4

For example Let p(x) = x + 4

Then the graphical representation of p(x) is a straight line which cuts X axis at ( - 4,0)

Also the zero of p(x) is - 4
