Question

when a = 0, b = -1, find the value of the given expressions. 2a square +b square + 1

Answer 1

2 (a^2)+b^2+1
=2 (0)+(-1)^2+1
=0+1+1
=2

HOPE IT HELPS!!

Answer 2

a=0
b=(-1)

given 2a square + b square + 1
=2(0)square + (-1)square +1
=0 + (-1)(-1) + 1

now we know
multiplication of two negative numbers is positive
so multiplication of (-1) & (-1) is positive 1

therefore
(-1)(-1)=1

so answer is
=1+1
=2

so, answer of the given expression is 2.
