Let us see if you all can get this: 21x² - 43x - 14 and 21x² - 43x - 14
factor these quadratic expressions, and in the end, tell me what method you used. finally, tell me which method you thought was the fastest:
1. slide & divide
2. group by group: greatest common factor [gcf]

Answer this question only if you know the 30 points and

Question 9 of 10 2 points suppose your sat score is 1770. you look up the average sat scores for students admitted to your preferred colleges and find the list of scores below. based on your sat score of 1770, which average score below represents the college that would be your best option? o a. 1790 o b. 2130 o c. 2210 od. 1350

Talia grouped the terms and factored out the gcf of the groups of the polynomial 15x2 – 3x – 20x + 4. her work is shown below. (15x2 – 3x) + (–20x + 4) 3x(5x – 1) + 4(–5x + 1) talia noticed that she does not have a common factor. what should she do?
