Question

question factor completely. 49 - 144x^2 answer attempt 2 out of 2

Explanation:

Step1: Recognize difference - of - squares

The expression $49 - 144x^{2}$ is in the form $a^{2}-b^{2}$, where $a = 7$ ($7^{2}=49$) and $b = 12x$ ($(12x)^{2}=144x^{2}$).

Step2: Apply difference - of - squares formula

The formula for $a^{2}-b^{2}$ is $(a + b)(a - b)$. Substituting $a = 7$ and $b = 12x$, we get $(7 + 12x)(7-12x)$.

Answer:

$(7 + 12x)(7 - 12x)$
