Question

if(a-b)=0.9 and (ab)=0.36, find the value of ( asqure-bsqure)​

Answer 1

Answer:

-step explanation: (a-b)=0.9, (ab)=0.36

ab=0.36 , a=0.36/b a-b=0.9, 0.36/b-b=0.9. 0.36-b^2=0.9b , -(b^2+0.9-0.36)=0 b(b+1.2)-0.3(b+1.2)=0 (b-0.3)(b+1.2)=0 b=0.3 , b=-1.2 a=0.12. (a^2-b^2)=(0.12^2-0.3^2)= -0.0756
