Question

if x is equal to 1 is a common root of the equation ax square + a x + 3 is equal to zero and X square + X + b is equals to zero then ab is​

Answer 1

Answer:

Step-by-step explanation:

given: x= 1

ax2+ax+3= 0

putting x=1

a+a+3=0

or, 2a+3=0

or, a=(-1.5)

similarly putting x=1 in x+x+b=0

we get,

b=(-2)

so, ab= 3

Hope it helps u

Answer 2

Answer:

a=-3/2 b=-2

Step-by-step explanation:

if x=1 then,

1) a(1)^2+a(1)+3=0

a+a+3=0

2a+3=0

a=3/2

2) 1^2+1+b=0

1+1+b=0

2+b=0

b=-2

ab=-3/2*-2
