Week 11 in math 10

Calum on

For me, since I was away on the thursday of week 10 when we learned ugly trinomials, the review we did on tuesday was the most important thing I learned this week. It was the most important thing I learned because I was always wondering how to factor trinomials with a coefficient since we started on factoring with the straight up x^2 at the front and I was confused about how we would do the ones with a coefficient, how you do them is by multiplying the coefficient with the constant and then finding the perfect factors with that number and the middle point, and then you put them in a box and find the GCFs of all the pairs and you then have your answer.

This week we learned how conjugates simplify in binomials, IE (x+4)(x-4) it will always have 2 terms and the second will be a negative constant so (x+4)(x-4) = x^2-16 and it will always be a negative perfect square on the end no matter what. These are important time savers because this will make it (if I recognize I can do it) so I can skip straight to my answer in simplifying rather than having to go through the writing it down and adding like terms and such.

Week 9 in math 10

This week the most Important thing is factoring polynomials because it allows me to work backwards on a simplified polynomials to find out dimensions of an object. I feel this is important because it could be something you actually see in real life situations where you will need to find out a good formula for exactly what sides need to be and can make life a lot easier when you’re trying to work from the ground up.
