Find the value of the discriminant. Then describe the number and type of roots for the equation.
-3x^2-18x+2=0

A. The discriminant is -348. Because the Discriminant is less than 0 the two roots are complex
B. The discriminant is 348. Because the Discriminant is greater than 0 and is not a perfect square the roots are real and irrational
C. The discriminant is -300 because the discriminant is less than 0 the two roots are complex
D. The discriminant is 324 because the discriminant is greater than 0 and is a perfect square the two roots are real and rational

Sagot :

Panoyin
Discriminant = b² - 4ac
Discriminant = (-18)² - 4(-3)(2)
Discriminant = 324 + 24
Discriminant = 348

It is B.
