How do i solve using the rational root theorem. 2x3-9x2-11x+8=0

1 answer:

4 0

2(3)-9(2)-11x+8=0
(2)(3)-(9)(2)-11x+8=0
6+-18+-11x+8=0
(-11x)+(6+-18+8)=0 Combine Like Terms.
-11x+-4=0
-11x-4=0
Add 4 to both sides.
-11x-4+4=0+4
-11x=4
Divide both sides by -11.
-11x/-11=4/-11
x=-4/11

Hope this helps!

taurus [48]

Step-by-step explanation:

<h2>GIVEN:-</h2>

The Perimeter of Equilateral triangle = 60cm

<h2>UNDERSTANDING THE CONCEPT:-</h2>

According to the question,

To find the height of the triangle,

Perimeter of Equilateral triangle = Area of Equilateral triangle.

<h2>FORMULA USED:-</h2>

$60 = \frac{ \sqrt{3} }{4} a {}^{2} \\$

<h2>REQUIRED ANSWER:-</h2>

$60 \times 4 = \sqrt{3a {}^{2} }$

$a {}^{2} = 240 \sqrt{3} \\$

$a = 120 \sqrt{3} cm$

<h3>SO, The Exact height of the triangle is 120√3cm.</h3>
