Find and correct the errors in the statement: 3x^2 / 3x^2 = 0
Answers
Given :
3x²/ 3x² = 0
Concept :
Common errors we done by solving algebraical expression and equation:
Error 1
Coefficient 1 of a term is usually not written. So we often ignore that. But while adding like terms, we should include it in the sum.
Error 2
When we multiply the expression enclosed in a bracket by a constant (or a variable) outside, we usually applied the multiplication to the first term only. This is the wrong calculation. Each term of the expression has to be multiplied by the constant (or the variable).
Error 3
when we square a monomial, we usually ignored the numerical coefficient. This is the wrong method. The numerical coefficient and each factor has to be squared.
Error 4
when we square a binomial, we usually do not apply the proper identity. This is the wrong approach. The right identity should be used.
Error 5
While dividing a polynomial by a monomial, We usually don’t divide each term of the polynomial in the numerator by the monomial in the denominator.
Solution:
3x²/ 3x² = 0
LHS = 3x²/3x² = 1
RHS = 0
LHS ≠ RHS
Correct statement :
3x²/ 3x² = 1

Answer:
L.H.S. = (3x + 2)2
= (3x)2 + 2(3x)(2) + (2)2 [(a + b)2
= a2 + 2ab + b2]
= 9x2 + 12x + 4 ≠ R.H.S The correct statement is (3x + 2)2 = 9x2 + 12x + 4
