Factor. 9p^2 - 12p + 4 ______

Identify Perfect Square Trinomial: Identify if the quadratic can be factored using the perfect square trinomial formula. A perfect square trinomial is in the form (a^2 ± 2ab + b^2) which factors to (a ± b)^2. Check if 9p^2 - 12p + 4 is a perfect square trinomial. 9p^2 is a perfect square, as (3p)^2 = 9p^2. 4 is a perfect square, as 2^2 = 4. The middle term, -12p, is twice the product of the square roots of the first and last terms, as 2 * 3p * 2 = 12p. Thus, 9p^2 - 12p + 4 is a perfect square trinomial.Check for Perfect Square Trinomial: Factor the perfect square trinomial using the formula (a^2 - 2ab + b^2) = (a - b)^2. Here, a = 3p and b = 2. So, (3p)^2 - 2 * 3p * 2 + 2^2 = (3p - 2)^2. Therefore, the factored form of 9p^2 - 12p + 4 is (3p - 2)^2.

9p^2 - 12p + 4

Identify Perfect Square Trinomial: Identify if the quadratic can be factored using the perfect square trinomial formula. $\newline$ A perfect square trinomial is in the form $(a^2 \pm 2ab + b^2)$ which factors to $(a \pm b)^2$ . $\newline$ Check if $9p^2 - 12p + 4$ is a perfect square trinomial. $\newline$ $9p^2$ is a perfect square, as $(3p)^2 = 9p^2$ . $\newline$ $4$ is a perfect square, as $2^2 = 4$ . $\newline$ The middle term, $-12p$ , is twice the product of the square roots of the first and last terms, as $2 \times 3p \times 2 = 12p$ . $\newline$ Thus, $9p^2 - 12p + 4$ is a perfect square trinomial.
Check for Perfect Square Trinomial: Factor the perfect square trinomial using the formula $(a^2 - 2ab + b^2) = (a - b)^2$ . Here, $a = 3p$ and $b = 2$ . So, $(3p)^2 - 2 \times 3p \times 2 + 2^2 = (3p - 2)^2$ . Therefore, the factored form of $9p^2 - 12p + 4$ is $(3p - 2)^2$ .
