Question

Q.1 If I is a root of the equations ay + ay + 3 = 0 and y2 + y + b = 0, then
find the value of ab.​

Answer 1

Answer:

so if the 1 is the root i.e we have to put 1 at the place of (y), we get value of a from equation 1 and the value of b from equation 2

so,

ay+ay+3=0

a1+a1+3=0. (y=1)

2a+3=0

2a=-3

a=-3/2

for (b)

1(2)+1+b=0. (y=1)

2+1+b=0

3+b=0

b=-3
