Factor x^2+3x+9/4

Problem

x2+3*x+9/4

Solution

1. Identify the expression as a quadratic trinomial of the form a*x2+b*x+c where a=1 b=3 and c=9/4

2. Check for a perfect square trinomial pattern, which follows the form a2+2*a*b+b2=(a+b)2

3. Verify the terms by noting that the first term is x2 and the last term is (3/2)2

4. Confirm the middle term by calculating 2⋅x⋅3/2 which equals 3*x

5. Apply the perfect square formula to write the factored form.

Final Answer

x2+3*x+9/4=(x+3/2)2
