If a=1 b=1 d=3 then can I say a+b(a+b)=d-b(d-b) ?

Question

Is it mathematically correct as it is?

Answer 1

no it's not.
keep in mind you do have to do multiplication first &brackets even before that. [Brackets Of Division Multiplication Addition and Subtraction]
1+1(1+1)=3-1(3-1)
1+2=3-2
3 [does not] = 1

Answer 2

LHS
a + ba + b² = 1 + 1 + 1 = 3
RHS
d - bd + b² = 3 - 3 + 1 = 1

LHS does NOT equal RHS.

Answer 3

See it depends on numbers u take if u take the number u have given than the statement is right but if u take an other number then the the statement is quiet wrong
