Verify
x-(-y)=x+yIfx=5andy=3
Here we have
So,
5-(-3)=5+3⇒5+3=8⇒8=8
Hence verified
Find the following products and verify the result for x = -1, y = - 2:
(3x−5y)(x+y)
Verify that x×(x−z)=x×y−x×z,if(i) x=45,y=−74~and z=3(ii) x=34,y=89~and z=−5
Verify that(x+y)×z=x×z+y×z,if(i) x=45,y=−23~and z=−4(ii) x=2,y=45~and z=3−10
