Daily Updated Notes
Started Of...Started off in class with reviewing the worksheet that was given out yesterday. Answered questions that students had and moved on to a new concept. Learning how to go from standard from to vertex form and how to factor it out and find the x intercepts. There was also another worksheet passed out, that is not due as far as we know. NotesSame concept as yesterdays, but with negatives.
Also, and equation (b/2)^2 is helpful. x^2 + 2x - 3 = 0. First add on both side to get x isolated. But. when you do that, another number will replace where 3 was. You'll replace it with 1. Now you have a oerfect square, meaning you can put it into standard form. x^2 + 2x + 1 = 4 ---> (x+1)^2 = 4. Now square root both sides to get rid of the squared, and you will have a negative & a positive 2 = x+1. Subtract 1 on both side. 2-1 = 1 & -2 - 1 =-3. -3 and 1 are your x intercepts.
