Answer»

Answer:

Steps:

1) Draw a LINE segment AB of length 9.3 units.

2) Extend the line by 1 unit more such that BC=1 unit .

3) Find the midpoint of AC.

4) Draw a line BD perpendicular to AB and LET it intersect the semicircle at POINT D.

5) Draw an arc DE such that BE=BD.

Therefore, BE=

9.3

units

Step-by-step explanation:

GIVEN,

Zeroes are 1/2+2√3 and 1/2-2√3

SUM of zeroes = 1/2+2√3 + 1/2-2√3

= 1/2 + 1/2

= 1

product of zeroes = 1/2+2√3 x 1/2-2√3

= [ 1/2 ] ² - [ 2√3 ]²

= 1/4 - 12

= 1/4 - 48 / 4

= -47 /4

Quadratic equation

x² - [ sum of zeroes ]x + product of zeroes

=x² - x + -47/4............
