The zeros of the function are also called the roots. Thus, this problem is basically locating the root of the given equation.

To locate the roots, we equate the equation f(x) to 0.

We then dissect each term to identify a, b, and c in the quadratic equation formula:

x = (- b +- √(b²-4ac))/2a

a = 2
b = 8
c = -3

x1 = 0.3452
x2 = -4.345

Use the table.
zubka84 [21]

Solution:

The table which is about kind of jeans and it's color is

Style       Color  

regular      light blue  

loose fit    indigo  

boot cut     washed  

slim fit       black

 slim fit     blue

(a) A regular can be chosen out of five  colors, A loose fit can also be chosen in five colors,Similarly a boot cut as well as slim fit can also  be chosen out of five colors.

If you consider this as a relation , total number of relation that is total jeans =  1×5 + 1×5 +1×5+1×5= 20 Jeans = 10 Pairs of jeans(Possible)

(b)  Total number of jeans , if i have one pair of jeans of each possible style and color = As there are 5 colors and 4 styles , the jeans are in pair = 5×4×2=40

Number of Black color jeans = 2× black color in  4 styles= 2×4=8

Probability of an event = \frac{\text{Total possible outcome}}{\text{Total favorable outcome}}

Probability of choosing a pair of black jeans at random=\frac{8}{40}=\frac{1}{5}
