Simplifying the Expression: (2x+1)^2 + 2(4x^2-1) + (2x-1)^2
This expression involves squaring binomials and simplifying terms. Let's break down the process step-by-step:
Expanding the Binomials
First, we'll expand the squared binomials using the formula (a + b)^2 = a^2 + 2ab + b^2 and (a - b)^2 = a^2 - 2ab + b^2:
- (2x + 1)^2 = (2x)^2 + 2(2x)(1) + (1)^2 = 4x^2 + 4x + 1
- (2x - 1)^2 = (2x)^2 - 2(2x)(1) + (1)^2 = 4x^2 - 4x + 1
Substituting and Simplifying
Now, let's substitute the expanded forms back into the original expression:
(2x+1)^2 + 2(4x^2-1) + (2x-1)^2 = (4x^2 + 4x + 1) + 2(4x^2 - 1) + (4x^2 - 4x + 1)
Next, we distribute the 2:
(4x^2 + 4x + 1) + 8x^2 - 2 + (4x^2 - 4x + 1)
Finally, combine like terms:
(4x^2 + 8x^2 + 4x^2) + (4x - 4x) + (1 - 2 + 1)
The Simplified Expression
After simplifying, we are left with:
16x^2
Therefore, the simplified form of the expression (2x+1)^2 + 2(4x^2-1) + (2x-1)^2 is 16x^2.
