PROBLEM

Simplify the expression 4x24+3xx2+1\frac{4}{x^{2}-4}+\frac{3x}{x-2}+1.

STEP 1

Assumptions1. The expression to be simplified is 4x4+3xx+1\frac{4}{x^{}-4}+\frac{3 \cdot x}{x-}+1.
. We are allowed to use the algebraic rules of simplification.

STEP 2

We can simplify the expression by first factoring the denominator of the first term.
x24=(x2)(x+2)x^{2}-4 = (x-2)(x+2)So, the expression becomes4(x2)(x+2)+xx2+1\frac{4}{(x-2)(x+2)}+\frac{ \cdot x}{x-2}+1

STEP 3

Next, we can find a common denominator for the fractions. In this case, the common denominator is (x2)(x+2)(x-2)(x+2).So, we rewrite each term with the common denominator(x2)(x+2)+3x(x+2)(x2)(x+2)+(x2)(x+2)(x2)(x+2)\frac{}{(x-2)(x+2)}+\frac{3 \cdot x \cdot (x+2)}{(x-2)(x+2)}+\frac{(x-2)(x+2)}{(x-2)(x+2)}

STEP 4

Now, we simplify the numerators4+3x2+6x+x24(x2)(x+2)\frac{4 +3x^{2} +6x + x^{2} -4}{(x-2)(x+2)}

STEP 5

Combine like terms in the numerator4x2+x(x2)(x+2)\frac{4x^{2} +x}{(x-2)(x+2)}

SOLUTION

Factor out the common factor in the numerator2x(2x+3)(x2)(x+2)\frac{2x(2x +3)}{(x-2)(x+2)}This is the simplified form of the original expression.
