The correct answer for this question would be the last option. The complete factor of 25x^2 – 36 is <span>(5x – 6)(5x + 6). To check, multiply both values. 5x times 5x is 25x^2, and -6 times 6 is -36. Which gives us 25x^2-36. Hope this answers your question. Let me know if you need more help next time.</span>
