Verify
(-x)+(-y)=-(x+y)ifx=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 the property : x+y=y×x by taking:
(i) x=−13,y=27
(ii) x=−35,y=−1113
(iii) x=2,y=7−8
(iv) x=0,y=−158
