To draw a graph of a quadratic polynomial and observe:- in) The shape of graph when the coefficient of x^(2) is positive ii) The shape of graph when the coefficient of x^(2) is negative iii) Its zero.

Answer»

The Graph of a Quadratic Polynomial and its observations are as follows:

Let us consider a quadratic equation for example,
x² + 2x + 4 = 0 and -x² + 2x + 4 = 0
i) The SHAPE of the CURVE when the coefficient of x2 is positive
x² + 2x + 4 = 0
x = -1 + √3 i , -1 - √3 i
The shape of the curve is UPWARD opening parabolic curve.
ii) The shape of the curve when the coefficient of x2 is negative
x² + 2x + 4 = 0
x = 1 - √5 , 1 + √5
The shape of the curve is a DOWNWARD opening parabolic curve.
iii) The shape of the curve when the coefficient of x2 is zero
0² + 2x + 4 = 0
2x + 4 = 0
x = -4/2
x = -2
The shape of the curve is a straight line.

The lenght of rectangle field is 140m.if ratio of length to breadth of the fiels is5:3then find breadth of field

Answer»

Step-by-step explanation:

LET length be 5×x m = 5X m

Breadth is 3×x m = 3x m

Length is 140 m

By CONDITION

5x = 140

x = 140/5

x = 28

So the breadth is (3×28) m = 84 m
