Answer 2

Answer:

value of is -3 ( 7 + b ) + ( 12 + 2b )√3

Step-by-step explanation:

Given Quadratic Equation, x² + bx + c = 0

          3 - 2√3 is root of given equation.

To find: Value of c

3 - 2√3 is root of given equation

⇒ It satisfy the given equation

⇒ ( 3 - 2√3 )² + b( 3 - 2√3 ) + c = 0

    3² + (2√3 )² - 2 × 3 × 2√3 + 3b - 2b√3 + c = 0

    9 + 12 - 12√3 + 3b - 2b√3 + c = 0

    c = -9 - 12 + 12√3 - 3b + 2b√3

    c = -3 ( 7 + b ) + ( 12 + 2b )√3

Therefore, value of is -3 ( 7 + b ) + ( 12 + 2b )√3
