Check Perfect Square Trinomial: Determine if the quadratic can be factored using the perfect square trinomial formula.A perfect square trinomial is in the form (a2±2ab+b2), which factors to (a±b)2.The given quadratic is 4v2−12v+9.We can check if 4v2 is a perfect square, which it is since (2v)2=4v2.We can check if 9 is a perfect square, which it is since 32=9.We can check if −12v is twice the product of the square roots of 4v2 and 9, which it is since (a±b)20.So, the quadratic is a perfect square trinomial.
Write in Correct Form: Write the quadratic in the form of (a2±2ab+b2).The given quadratic is already in this form: (2v)2−2×2v×3+32.
Factor Using Formula: Factor the quadratic using the perfect square trinomial formula.Since we have a minus sign in the middle term, we will use the formula (a−b)2=a2−2ab+b2.The factored form is (2v−3)2.
