Answer:
Which of the following quadratic has negative discriminant?
Answer: a. 6x ^ 2 - 9x + 12 = 0
which of the quadratic equations has zero discriminant?
Answer: a. x² - 4x + 4 =0
Which of the following is the standard form of quadratic equations?
Answer: b. ax²+bx+c=0,a=0
Step-by-step explanation:
For first question:
6x ^ 2 - 9x + 12 = 0
a= 6
b= -9
c= 12
b²-4ac
(-9)²-4(6)(12)
-207
For second question:
x² - 4x + 4 =0
a= 1
b= -4
c= 4
b²-4ac
(-4)²-4(1)(4)
0
