The value of x are; x = 5 + √(97)/12 and x = 5 - √(97)/12.
A quadratic equation is the second-order degree algebraic expression in a variable.
The standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
Given;
5x = 6x² - 3
Subtract 5x on both sides
5x - 5x = 6x² - 5x - 3
0 = 6x² - 5x - 3
x = -(-5) ± √((-5)² - 4(6)(-3)) / 2(6)
x = 5 ± √(25 + 72)/ 12
x = 5 ± √(97)/ 12
The value of x are;
x = 5 + √(97)/12
x = 5 - √(97)/12

Answer:
Step-by-step explanation:
In triangle if two sides are known and included angle is known we can use cosine formula as follows:
Say in a triangle, sides a,b are known and also included angle C
Then the third side
Since all values on right side are known, we can find the third side c easily.
Case II:
If alternately two sides and one angle not included is known. i.e we know a,b and either angle A or B.
then to find third side we use sine formula.
Using the above we can find the unknonwn side c easily.
