Question

if x=2/3 and x= -3 are the roots of the equation ax^2+7b+b =0 find the values of a and b​

Answer 1

Answer: a = 3, b = -6

Step-by-step explanation:

Expected Equation -> $ax^{2} +7x+b = 0$

Put x=2/3 and x = -3 in the equation

$4a+9b = -42 ....................(1)\\9a+b = 21....................(2)$

After solving,

a = 3, b = -6
