## Week 9 – finding “a”

All we do is plug in where the point is into the equation to find “a”

to find the standard or vertex form we have to complete the square. On the left side we put brackets in to separate the C to find the perfect square for the brackets to find the to find the standard

To find the discriminant we have to use we plug in the numbers and when we find the answer that is our discriminant. The discriminant tells us how many roots our equation has… so if x>0 we have two roots

This week in Pre-Calc 11 we learned how to factor trinomials and it is fairly easy

This week in Pre-Calc 11, we learned how to solve using the Quadratic formula

This week in math, we had learned how to rationalize fractions and it is quite easy. For radicals being in the denominator you have to get rid of it. You would have to multiply the fraction by the radical over

This week we had learned about absolute values and simplifying radicals. For absolute values we had learned about whatever is in-between the two lines will always be positive. = 8 To simplify radicals you have to know the root. Either

In Week 1 we had learned about Arithmetic Sequences. This week we had learned about Geometric Sequences. Both of these are different as Arithmetic is addition of a positive or negative number of a common difference and Geometric is multiples
