Question

if x=1 is a common root of ax²+ax+2=0 and x²+x+b=0,then ab=? explain

Answer 1

★ Hey mate★

here is your answer!!


x = 1


on putting the value in equations we get


a ( 1 )² + a × 1 + 2 = 0

a + a + 2 = 0


2a = -2


a = -1


now ,


x² + x + b = 0


( 1 )² + 1 + b = 0


b = -2




ab => - 1 × -2


ab = 2



hope it helps you dear !!!
