<u>Answer:</u>
are two roots of equation
<u>Solution:</u>
Need to solve given equation using quadratic formula.
General form of quadratic equation is
And quadratic formula for getting roots of quadratic equation is
In our case b = -1 , a = -3 and c = -3
Calculating roots of the equation we get
Since is equal to -35, which is less than zero, so given equation will not have real roots and have complex roots.
There are several information's already given in the question. Based on those given information's the answer can be easily deduced.
Lateral area of the solid = 216 cm^2
Lateral edge of the solid = 9 cm
Let us assume the measure of the one side of the section = x
Then
216 = 4s * 9
216 = 36s
s = 6
From the above deduction, it can be concluded that the measure of the one side of the section is 6 cm. I hope that the answer has actually come to your help.
