Answer:
Option D.
The discriminat is equal to 24 which
Step-by-step explanation:
The quadratic equation is
-2x² + 3 = 0
Discriminat in quadratic equation tells us the number of solution a quadratic equation has.
For example, the quadratic equation
Ax² + bx + c = 0 will have a discriminat of b² - 4ac.
b² - 4ac is equal to the value of the discriminat and equal to the number of solutions the quadratic equation has.
In our question, we have -2x² + 3 = 0
A = -2
B = 0
C = 3
b² - 4ac = 0
Substitute the values into the above equation.
0² - 4(-2 ×3) = 0
0 + -4 × -6 = 0
24 = 0
The discriminat of the equation is 24
Answer: 1320
Step-by-step explanation:
Given,
HCF of two numbers = 40
Product of two numbers = 52800
To find,
LCM of two numbers =?
Formula required,
HCF × LCM = product of two numbers
Calculation,
Using formula
→ HCF × LCM = product of two numbers
→ ( 40 ) × LCM = 52800
→ LCM = 52800 / 40
→ LCM = 1320
Therefore,
LCM of two numbers would be 1320.
