Question

. If the equation 2x – 3y + 4 = 0 is compared with ax + by + c = 0, then the value of a2

– b2

– c2 is​

Answer 1

Answer:

- 21

Step-by-step explanation:

2x – 3y + 4 = 0

Here,

a = 2

b = - 3

c = 4

a^2 - b^2 - c^2

= 2^2 - ( - 3 )^2 - ( 4 )^2

= 4 - 9 - 16

= 4 - 25

= - 21

Answer 2

Step-by-step explanation:

• a=2,b= -3 ,c=4
