Question

P(x) =x2 +3x -4 draw the graphs given polynomials and find zero

Answer 1

P(x) = x²+3x-4

suppose that the value of x is 1 then

P(1)=(1)²+3(1)-4

P(1)=1+3-4

P(1)=0

GX is the factor of px

Answer 2

The zero of the polynomial is -4 and 1.

Step-by-step explanation:

Given : Polynomial $P(x) =x^2 +3x -4$

To find : Draw the graphs given polynomials and find zero ?

Solution :

$P(x) =x^2 +3x -4$

Refer the attached graph below.

The graph is a upward parabola as it is quadratic equation.

The curve passes through (-4,0) and (1,0).

The zero of the polynomial is where the curve cut the x-axis.

i.e. the zero of the polynomial is -4 and 1.
