Question 701663: Hello,
I am a student who is in Grade 11 and in Mathematics Grade 11 Foundations. We are currently reading and studying algebra, factors, power, quadratics, binomials, algebra, and linear equations. Right now, we are studying factoring and powers.
This weekend, we got a big assignment on powers and factoring for math which is due on Monday and it is worth 80 marks. I got all of the answers right, but I am very stuck on the last question. I tried doing it and spent a lot of time on it, but I am still stuck, very confused, and I do not understand it. Could you please help me. Thank you.
Here is the question:
Factor each trinomial:
144x^2 - 64m^2

Please solve this question, and send the solved question to me on my email, which is a-m-m.m@hotmail.com once you have solved the question.
Thanks again for your time and help, I greatly appreciate it. Thank you.
Allen

You should memorize the result:
+a%5E2-b%5E2=%28a%2Bb%29%28a-b%29+

This is of this form, as:
+144x%5E2+-+64m%5E2+=+%2812x%29%5E2+-+%288m%29%5E2+=+%2812x%2B8m%29%2812x-8m%29+
