# Find and correct the errors in the statement: (2x)^{2 } + 4(2x) + 7 = 2x^{2 }+ 8x + 7

**Solution:**

An equation is a mathematical statement with an 'equal to' symbol between two algebraic expressions that have equal values.

Given,

(2x)^{2 } + 4(2x) + 7 = 2x^{2 }+ 8x + 7

Solving LHS we get,

(2x)^{2} + 4(2x) + 7

= 4x^{2} + 8x + 7

But RHS = 2x^{2 }+ 8x + 7

Thus, L.H .S. ≠ R.H.S.

The correct statement is (2x)^{2} + 4(2x) + 7 = 4x^{2} + 8x + 7
