Determine Approach: Determine the approach to factor the quadratic expression t2+4t+4. We can use the perfect square trinomial formula: (a+b)2=a2+2ab+b2, since the expression resembles a perfect square trinomial.
Identify Values: Identify the values of a and b that would make the expression a perfect square trinomial.For the expression t2+4t+4, we can see that a=t and b=2 because:a2=t22ab=2×t×2=4tb2=22=4So, t2+4t+4 is in the form of a2+2ab+b2.
Factor Expression: Factor the expression using the perfect square trinomial formula.Since we have identified a=t and b=2, we can write the factored form as:(t+2)2This is because (t+2)(t+2)=t2+2t+2t+4=t2+4t+4.
