Question

5. When a= 0,b=- 1. find the value of the given expressions:
(1) 2a + 2b
(i) 2a + b + 1
(ii) 2ab + 2ab2 + ab
(iv) a² + ab +2
​

Answer 1

Answer:

solution of 1

$0+2(-1)=-2$

solution of 2

$0-1+1=0$

solution of 3

$2(0)(-1)+2(0)(-1)2+(0)(-1)$

0+0+0=0

solution of 4

${0}^{2} + (0)( - 1) + 2 \\ = 0 + 0 + 2 = 2$
