Question

3. 5x = 2(y - 1) is not a linear equation in two variables.
The
formula
to find the discriminant D of the quadra​

Answer 1

Answer:

b^2 - 4ac

Step-by-step explanation:

5x = 2y - 2

5x + 2y + 2 = 0

by comparing with ax + by + c =0

a=5 b=2 c=2

therefore,

b^2 - 4ac

2^2 - 4 × 5 × 2

4 - 40
