Factor. 25w^2 - 30w + 9 ______

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 (a^2 ± 2ab + b^2) = (a ± b)^2. We need to check if 25w^2 - 30w + 9 fits this pattern. 25w^2 is a perfect square, as it is (5w)^2. 9 is a perfect square, as it is 3^2. The middle term, -30w, should be equal to 2 times the product of the square roots of the first and last terms if it is a perfect square trinomial. 2 * 5w * 3 = 30w, but we have -30w, so it still fits the pattern with a negative sign.Write as Perfect Square: Write the expression as a perfect square trinomial. Since we have established that 25w^2 - 30w + 9 is a perfect square trinomial, we can write it as: (5w)^2 - 2 * 5w * 3 + 3^2 This confirms that the expression is indeed a perfect square trinomial.Factor Trinomial: Factor the perfect square trinomial. Using the formula (a^2 - 2ab + b^2) = (a - b)^2, we can factor the expression as: (5w - 3)^2 This is the factored form of the quadratic expression.

25w^2 - 30w + 9

Check Perfect Square Trinomial: Determine if the quadratic can be factored using the perfect square trinomial formula. $\newline$ A perfect square trinomial is in the form $(a^2 \pm 2ab + b^2) = (a \pm b)^2$ . We need to check if $25w^2 - 30w + 9$ fits this pattern. $\newline$ $25w^2$ is a perfect square, as it is $(5w)^2$ . $\newline$ $9$ is a perfect square, as it is $3^2$ . $\newline$ The middle term, $-30w$ , should be equal to $2$ times the product of the square roots of the first and last terms if it is a perfect square trinomial. $\newline$ $2 \times 5w \times 3 = 30w$ , but we have $-30w$ , so it still fits the pattern with a negative sign.
Write as Perfect Square: Write the expression as a perfect square trinomial. $\newline$ Since we have established that $25w^2 - 30w + 9$ is a perfect square trinomial, we can write it as: $\newline$ $(5w)^2 - 2 \times 5w \times 3 + 3^2$ $\newline$ This confirms that the expression is indeed a perfect square trinomial.
Factor Trinomial: Factor the perfect square trinomial. $\newline$ Using the formula $(a^2 - 2ab + b^2) = (a - b)^2$ , we can factor the expression as: $\newline$ $(5w - 3)^2$ $\newline$ This is the factored form of the quadratic expression.
