Mathematics

Step 1. Calculate the discriminant:
\Delta =  b^2 - 4ac

Step 2.
If \Delta>0, there are two solutions, both real numbers
If \Delta=0, there is only one solution, real number
If \Delta, there are two solutions, both complex numbers

In your case:
a=3, b=6, c=4
\Delta = 6^2 - 4 \cdot 3 \cdot 4 = -12

So you have two solutions, both complex numbers

I hope this helps you



3x^2+6x+4=0


a=3 b=6 c=4



disctirminant=b^2-4ac



disctirminant=6^2-4.3.4


disctirminant=36-48


disctirminant= -12


x1= -6+ square root of -12/2.3



x1= -6+2i square root of 3/6



x1= -3+i square root of 3/3


x2= -6-2i square root of 3/6


x2= -3-I square root of 3/3

The largest possible circle is cut out of a square whose side length is 8 feet. What will be the approximate area, in square fee
valentina_108 [34]
<h3>Therefore the area of remaining board  =13.76 square feet</h3>

Step-by-step explanation:

Given , The length of side of the square is 8 feet.

Since a circle is inscribed in the square. Then the diameter of the circle is equal to the length of side of the square .

Therefore the diameter of the circle is = 8 feet.

Radius of the circle is(r) = \frac{8}{2} feet = 4 feet

The area of the circle is= 3.14 r²

                                       = 3.14 × 4² square feet

                                      = 50.24 square feet

The area of the square  is = side × side

                                          = 8×6 square feet

                                          =64 square feet

Therefore the area of remaining board = (64- 50.24)square feet

                                                                 =13.76 square feet
