Check for Perfect Square Trinomial: Determine if the quadratic expression can be factored as a perfect square trinomial. A perfect square trinomial is in the form (a+b)2=a2+2ab+b2. We need to check if 4m2+12m+9 fits this pattern.
Identify a2, 2ab, b2: Identify a2, 2ab, and b2 in the expression 4m2+12m+9.a2=4m2, which suggests that a=2m.b2=9, which suggests that 2ab0.To fit the pattern, 2ab should equal 2ab2.
Verify 2ab Calculation: Verify that 2ab equals 12m using the values of a and b identified in Step 2.2ab=2×2m×3=12m.This matches the middle term of the quadratic expression, confirming that it is a perfect square trinomial.
Write Factored Form: Write the factored form of the quadratic expression using the values of a and b. Since a=2m and b=3, the factored form is (a+b)2=(2m+3)2.
