Question

SOLVE BY DETERMINANT FORMULA
1.
$b {}^{2} - 4ac$
2.
$- b \times \frac{ + }{ - } \sqrt{b { }^{2} - 4ac }$



$x {}^{2} + 9 \sqrt{3} x + 24$
​

Answer 1

Answer:

By discriminant formula...

D = b²-4ac

a = 1, b = 9√3, c= 24

D = (9√3)²-4×1×24

D = 243-96

D = 147

Answer 2

$\huge\boxed{\fcolorbox{cyan}{red}{Ms~COWARD}}$

a = 1

b = 9√3

c = 24

By discriminant formula

D = b² - 4ac

D = ( 9√3 )² - 4 × 1 × 24

D = 81 × 3 - 96

D = 243 - 96

D = 147
