Answer 1

YOOO

HERE IS YOUR ANSWER

DISCRIMINATION WILL BE
2×2X+10+0
ANSWER IS:-4X+10

Answer 2

Answer:

So discriminant is -836

Step-by-step explanation:

The given quadratic equation is

2x²+ 10 x + 21 = 0

Now we know that if we have a quadratic equation

a x ² + bx + c = 0

Then the value with x ² is a , value with x is b and there is a constant c

and its discriminant is found by the formula

Discriminant = b ² - 4ac

Now in our given equation

a = 2

b = 10

c = 21

Now formula for discriminant is

Discriminant = b ² - 4ac

Putting in the values

Discriminant = 2 ² - 4(10)(21)

                      = 4 - 840

                       = - 836

So discriminant is -836
