Question 5 (ii)
When a = 0, b = -1, find the value of the given expression: 2a2+b2+1
2a2+b2+1=2(0)2+(−1)2+1 [Putting a = 0, b =-1] =2×0+1+1=0+2=2
Question 5 (iii)
When a = 0, b = -1, find the value of the given expression: 2a2b+2ab2+ab
When a = 0, b = − 1, find the value of the given expressions:
(i) 2a + 2b (ii) 2a2 + b2 + 1
(iii) 2a2 b + 2ab2 + ab (iv) a2 + ab + 2
Question 5 (i)
When a = 0, b = -1, find the value of the given expression: 2a + 2b
