Question

Plz solve this equation with explanation ​

Answer 1

Answer:

16

Step-by-step explanation:

Given quadratic equations

X^2 +2√3x -9 = 0

here ,a=1,b=2√3 and c= -1 so, the discriminate

(D)= b^2 - 4ac

(D)= (2√3) - 4(1) (-1)

(D)= 12 + 4

(D) = 16

As D >0,the roots of the eq are real and unequal
